My missing Art lens list is:
Sigma 12mm f/2.8 DG ART
Sigma 20mm f/1.8 DG ART
Sigma 24mm f/1.4 DG MACRO (1:3-ish) ART
Sigma 85mm f/1.4 DG ART
Sigma 135mm f/1.8 DG OS ART
Sigma 100-300 f/4 DG OS ART

Missing in this list is the 28mm, or is 28mm a dead prime focal length?

As a prime shooter, I don't really miss anything in-between 24mm and 35mm FLs :). Sigma has the old 28/1.8 DG Macro in their line up, which isn't that great on FF (actually, none of the 3 are). If I remember correctly, they released all three (20/1.8, 24/1.8 and 28/1.8 ) at the same time some 15 years ago. So, if they decide to remake all three lenses for their Art lineup, then 28mm would get the least of my attention, unless it would be superior optically by a reasonable amount. For me, something like a single 21/1.8 DG Art would be perfect :).

Actually the 20mm is a rear focus design and it doesn't change length when focusing. That makes it a bit of a different beast from its 24 and 28 mm siblings that have a front focusing design. I'm really satisfied with my copy by the way - it's a solid piece of glass that interestingly can generate quite nice bokeh when you use its near focusing ability.

Why do people keep thinking that a 24-70mm f/2 is even remotely likely?

Have they not held the already behemoth Canon 24-70 2.8 mk2 or Tamron 24-70 2.8 VC, both which require 82mm filter threads just to sharply render that zoom range at 2.8?

Have they not noticed that the Sigma 18-35mm f/1.8 DC is only a 2x zoom, not a 3x, and that it only needs to worry about a largest diaphragm of 35 / 1.8 and an APS-C image circle?  (HUGE difference from 70mm f/2 with an FX image circle!!)

Whether or not they actually make one, my point is that existing facts point to their being absolutely zero possibility / likelihood of it happening.  The whole thing was started as wishful thinking, and remains nothing more than just wishful thinking / urban myth, to this day.

Now a 16-24mm or 18-28mm f/1.8 FX, THAT I could get behind.  :-P

Hope dies last and if there is nothing really looking forwards to (clean iso 12800, f2 zooms, ...) you won't be able to satisfy your gear acquisition syndrome in the future, meaning severe withdrawal symptoms in the future.

Well, I didn't find any decent samples from Ʃ20mm f/1.8 when I was looking for something really wide and the reviews weren't very promising either. So I just skipped it and grabbed a Samyang 14/2.8UMC. However, I was considering the 12-24mm DG HSM zoom too, but Sigma's QC was awful back then. Crazy copy variation lottery wasn't very tempting, rather scary. Maybe Art version of 12-24mm is more realistic and reasonable expectation. The new(ish) Sigma 8-16mm DC HSM is very good.
And yeah, that macro feature is a very nice and unique selling point. I hope Sigma will include it in their next 24mm.

That feature alone make the 20mm Sigma a lens worth having IMHO. I consider it one of my specialty/fun lenses that may not win any technical awards but it sure is a great creative tool if used wisely.

I've attached two samples shot with this lens that show its capabilities.  Both shot with a 5D MkII.

Nice shots. But when I look closely I see f/8, the uniqueness is lost :) and the 20mm doesn't have that feature, or does it? I think it is 1:4+ at MFD, similar to many other wide angle lenses like 17-40L.

The MFD is shorter; 0.2m.

It is a lens I use rarely, so it's fine by my standards.

They are modestly sized lenses.  Not big at all.

18mm f/1.8 on crop is a harder thing to get to than 24mm and f/2.  This is because Sigma's crop lenses don't reach into the body like EF-s lenses do, so they have to have the regular back focus distance of a full-frame lens.  This makes 18mm much more strongly retrofocus than 24mm, and f/1.8 is still faster than f/2.  I doubt much in the 18-35 is driven by the aperture at the long end, and 70/2 is still only 35mm, which isn't very much aperture.  My 85/1.8 is silly tiny and has 47mm of aperture.

Nice sky in the second one. Now I can't stop thinking about this lens :). Could be GAS infection.

That's the way GAS works, anyway if you think your creativity is enhanced by such a lens, you should go ahead and buy one. I personally think the new price is a bit steep at the moment (€619 in the Netherlands, somehow this lens is getting more and more expensive to buy new) but it's a good lens to pick up second hand if you can find a nice and clean copy.

Sigma 20mm f/1.8 DG ART
Sigma 24mm f/1.4 DG MACRO (1:3-ish) ART
Sigma 85mm f/1.4 DG ART
Sigma 135mm f/1.8 DG OS ART
Sigma 100-300 f/4 DG OS ART
The Sigma 100-300 f/4 DG OS ART is an interesting option. I have the old one, but it is the worst lens I have and the only one of my lenses I would prefer not to buy. It is capable to give very good results. Sometimes... Look at any birds on my website: www.len-lex.com/gallery.asp - all ware taken with that lens. But sometimes it just keeps failing. E.g. I shoot in good light from tripod with remote release and fine-focusing with liveview, fast shutter, no wind or earthquakes, but the result is damn blurry! Very inconsistent. Maybe it is just a bad copy. Anyway, with current level of Sigma's lenses it is very interesting to see such lens reworked. And OS would be a very useful thing on it. Kinda love and hate story, which probably would be better with the renewed version :)
And if we speak about birding – 100-300 is too short actually. Even with TC x1.4. So the rumored 300-600mm f/? OS Sport would also be interesting. I hope it will be constant f/4. It is not an easy task, but really isn't something impossible for Sigma. What I would be even more interested to see is a refresh of their super-telephoto primes! I do hope one day to get something like 500mm f/4 IS, but Canon's options are insanely expensive. Something IQ-comparable from Sigma for half the price and I'm in! :)
Canon 7D, Canon 50D, Canon EF-S 60mm f/2.8 Macro, Tokina 11-16mm f/2.8, Sigma 100-300mm f/4 EX DG HSM, Sigma 18-35mm f/1.8 DC HSM | Art, Sigma 1.4X Teleconverter EX APO DG, Canon Speedlite 430EX II.

Yes, I remember all the old Σ100-300/4 reviews being very controversial, due to obvious reasons like bad QC and copy variation. Now, the new Σ120-300/2.8 is just crazy good (for a sigma zoom :) ), even with TCs. IMHO, the updated Σ100-300/4 (or 300-600mm) should be really good.
