No wide angle f2 zoom lenses? Not interested Canon.

Are you being serious?  Any idea how expensive or cumbersome said lens would be?

Sigma makes a 20mmf1.8 that's reasonably sized, and there's 24mmf1.4 lenses all over the place, how hard could 18mmf2 really be?
I agree though, to do a proper job the Nikkor 14-24 is probably a good example of the necessary size.
People would still love it though.

While I can understand the desire on a 1.6x crop. I really can'y see any benefit of an IS unit on a full frame 16mm lens. If you need stability....then use a tripod. Should anyone really be hand holding less than 1/15th sec? If the shot is that important....put it on a pod, end of story.

When I travel Europe, I love to photograph castles, churches, museums, (anything dimly lit and indoors) places that never allow pods of any kind.

I'd really hoped for the 16-50/4 IS ...  :(

I will love to have a 16-50 f/4 IS too. But I don't think that's coming. It is probably a figment of someone's imagination. Sigh

How about this source of imagination:

But that is a f5.6. I want a f4 :)

There were rumors before of a 16-50:http://www.canonrumors.com/?s=16-50+is] [url]http://www.canonrumors.com/?s=16-50+is[/url]

Not everyone wants to hike with a tripod. I do a lot of forest hikes where I go minimalistic on the equipment. Forest environments were tailored for UWA lenses. Having IS would be great.

Yes, and even if you can bring a tripod: if IS can do the job why not use it? It is both technology to help the photographer. I don't always know what position I get in and I don't want to carry a tripod all the time (IS is a lot easier).

Futhermore: IS is handy for (quick) 'creative' stills and video in general. Not all people want it but to say: "put it on a pod, end of story" ... no ...

Yes, please travel to Rome and use your tripod inside the Basilika St. Peter - i'm sure the Switzer Guard will show you how they use guys like you, their tripods an a handfull of vaseline...

Is size, cost, and weight the reasons someone would go with a 16-35 f/4 over the 16-35 f/2.8?

I like my 16-35mm f/2.8 a lot and haven't noticed any problems with it.
Do you use it for astrophotography fully open?

I have before.  Long exposures in national parks out West for instance.  I carried it down to the bottom of the Grand Canyon a few years ago (with a tripod even).

Well if you used it for astrophotography at 2.8 you will have seen coma in the form of stars looking like...seagulls  >:(  just like this guy:

The 17-40 definitely needs an upgrade. The Tamron 10-24 I had for apsC was sharper than my 17-40 on FF.

You are comparing two different lenses on two different formats. It's not a reasonable comparison.
Yes, there's room for an update. But it's not a critical update. The current 17-40L and 16-35IIL are both very strong and capable performers.

FF should be sharper than APS-C all other things being equal. the fact that I had better sharpness just means that the 17-40 is just that much worse.

I really hope they deliver on the 16-50mm f/4 IS.  That would really be something interesting and new.  It would make for a nice walk-around and landscape lens.  I've been building a whole new lens plan based on the idea of having one.

A super sharp 16-35mm f/4 would be okay, assuming it's priced right, but still a bit of let down.  The 35mm end would still be okay for a general purpose walk-around lens, but just a bit too wide to really feel like a fun general purpose lens.

They're bigger, heavier and more expensive. In the current climate, why (and how!) would you want to sell something to the consumer that is bigger, heavier and more expensive than what they already have with marginal improvement?

the only positive in this is the potential update for the 16-35 keeping f2.8
its my most used lens i shoot it wide open as much as stopped down
heres hoping it gets a makeover akin to the one the 24-70 got :D

How hard can it be? Surely the fact that no one has made one yet points to how hard it is.
Wide angle zoom lenses are notoriously hard to manufacturer. The internal elements tend to be very small and need a very high level of precision compared to longer focal lengths. Plus the need to retro focus on any lens wider than 35mm due to the SLR mirror box, just adds complexity to the over all design.
