That sounds all fine and good - but I still don't buy it. They've got no more in the wide-angle department than anyone else and still no EF-S fisheye. Their 10-22mm is no faster than Sigma's 10-20mm or Nikon's 10-24mm and not as wide as Tamron's 8-16mm. As far as I can tell, it's all negatives with no positives... especially if you want to "move up" to FF at some point; if you have a decent collection of EF-S lenses, you won't have much of an incentive to stick with Canon.
I didn't read it as making wider lenses; I read it as making the lenses that they do make better, cheaper and lighter. Nevertheless, you have a point. Still, it's neither good nor bad; just a choice, and one that isn't right for you. I wanted 8fps and $1000 in my pocket more than I wanted the image quality of the 5D II. That was the choice for me.
I still believe I have a decent incentive to stay with Canon if I decide to move up, for a couple reasons. First, I am comfortable with the feel of the cameras, and the menu. Second, there are still lenses that fit both bodies; any lens I would buy for a 5D would fit on my 7D and 40D. Right now, when I shoot at Steelers training camp, I have the 100-400 on the 7D, and the 17-55 on the 40D.
And finally, if I were primarily a landscape shooter, I would have absolutely made different choices. I would have gone for the image quality of full frame, and those awesome premium wide angle lenses that Nikon and Canon make (I have no preference for brand, I just happen to own Canon). But for what I do, this is what fits; this is the set of compromises that suits me. And I'm not concerned about the investment in EF-S lenses; they'll work as long as the cameras work. After all, if I have enough $$ to get that 5D Mk (x), I'm not going to let a new lens slip by me!
It's all good.
