One thing is for sure: Canon rumors are quantum leap better then Canon launches. Big LOL. 
Btw the lines, rumors don't materialize so often, as much as I wish.
The 35/1.4 II is on the top of my list for some time.
The 24-70 screwed with its price and lack of IS. Waitting for a big rebate, lower the price or 24-70 I or III. Not mentioning that I was expecting a larger focal distance; let's say 24-80.
The marketing man at Canon is completly dumb. Their strategy is more of keeping what they have, not evolving, not stilling market from Nikon, not to impress their loial customers. C'mon grandma! Nikon can do it, U don't ?
Let's look at their prime lenses lineup. I want to buy:
The 24 II exists and is very good. I'll buy it.
The 35 is god but not stellar compared to the 35/2.0 so it doesn't make much sense the L. The II is iminent.
The 50/1.4 it's lack of real USM and after 3 lenses tested the focus is little eratic and at f2.0 it's not that good. The Nikon counterpart is at least 1 step better.
The 50/1.2 is a big disappointment. The close focusing error; until f2.0 it's not up to an L. Sigma knows!
The 85/1.2 II - focusing speed and I said it all. The Nikon and Sigma are in a way better investments.
The 85/1.8 it's ok but not that good wide open.
The 135. We all are expecting IS on this as much as on every tele lens.
I agree you hit the nail on the head right there with those points! The only thing is I'm not overly fussed with no IS on the new 24-70/2.8 II but I know some people are really upset with that.
The new 35/1.4 II is definitely imminent. The current one - the bokeh is really busy and that's to do in part by the non-rounded aperture blades. When you've got L primes with 8 non-rounded blades, and zooms out there now with 9 rounded blades - you know the primes will soon get an upgrade.

The 24/1.4, 50/1.2 and 85/1.2 L lenses all have 8 rounded blades. The 35/1.4 doesn't have rounded aperture blades. Pick the odd one out that's due for an upgrade. I'll grab the mark II version.
The 135/2.0 also doesn't have rounded blades. This is another lens that's really due for that aperture blade upgrade. If they bolt IS onto it, then it's a guaranteed purchase for me. That'll be my street shooting tour de force! They had better keep it black though!! White lenses stand out like the proverbials on the street.
The 50/1.2. Yeah I've heard that about that lens, which is why I've steered clear of it. Must look at that Sigma again

The Canon 50/1.4. Great image quality but horrible horrible lens in all other respects. Do not buy! You could sit there for days with that thing hunting for focus with the centre AF point. Really disappointing lens. If only they'd put the 85/1.8's AF into it, it'd be sooo much better.
85/1.8. Owned that one as well. Awesome AF speeds, but CA CA CA! Soft wide as well, but the CA got me to upgrade to the 85/1.2.... which still has big CA but not as bad.
The new 35/1.4L and 135L will come.
What needs to come before any of those is a decent wide zoom! I'm hoping that Canon will bring out at least one of these three awesome wide-angle zooms this year:
14-24/2.8L (no filter thread)
16-40/4L
16-35/2.8LIII.
I want the 16-35/2.8L III but really I'm so desperate for a decent wide zoom I'll probably get whatever they release first. It'll finally be a lens with decent corner sharpness! Canon have proven with the 8-15/4 fisheye and new 24-70/2.8II that they can engineer wide zooms with decent corners.
Another lens they should update is the 24-105/4. I've gone to f/2.8 zooms, but that lens is still popular and Nikon have a 24-120/4 which I am envious of for travel. Pair that up with a couple of fast primes and you've got a pretty decent travel kit.
