Nothing has been taken care of as far as I am concerned. Until the 24-70 is in my hands it doesn't exist for me.
A 35L 1.4 IS upgrade would be superb. I'd like to see the holy trinity upgrades with IS and improved performance. although the 135 holds the least appeal for me, maybe upgraded to f 1.4 and given the super tele treatment?
35L is a great lens and I like using it, but it leaves something to be desired until stopped down to 2.8 or narrower. IS would help hugely at f/2.8-f/4 handheld in dark conditions.
85L 1.4 IS. This is a dream lens for me. I don't need 1.2 if it is slow to focus and doesn't deliver very good wide open performance. I've played around with the 85 1.2L II and while I see the appeal and think it should remain in the lens lineup, I think I would be better served by a faster, sharper, IS enabled 1.4 version.
135 1.4L IS. Sure, what the hell. Let's imagine it's a big honking white lens a la 200 f2L IS. But it's shorter at 135 and faster at 1.4.
Canon doesn't like to flat out replace lenses if they can help it. By adding IS and or reducing the widest aperture setting Canon can diversify its lens lineup without sacrificing the existing models.
Forget 10 (2 are super teles anyway), if I could pick 5 in 2011 here is my dream list in order of lust:
24-70 2.8L IS
35 1.4L IS
85 1.4L IS
24-120 4L IS
I don't know if any of these are realistic but
35mm f2.0 needs an update... (with USM or less noisy motor)
Also 35mm f1.4L with IS will be awesome.
And also it's good to know that
24-70mm f2.8L IS is coming
