Isn't that more a statement about where we are in the evolvement of digital capture than anything else? So far I see lots of ideas about the next big thing (ex. computational photography), but until that shows up we many not have much left but incremental changes.
I think it's more about marketing strategy. I'm essentially a Canon guy, although I also own a D700 and Nikkor 14-24 lens because the lens was so darned good I couldn't resist. But I'm not entirely happy about struggling with two different systems with different buttons to push.
In restrospect, I now feel I should have been less impetuous and opted for a 5D2 with the new TS-E 17mm which of course wasn't available at the time I bought the D700. Such is life!
The 14-24mm Nikkor is a different beast to the 17mm TS-E, but the fact remains, if a little birdie had whispered in my ear that Canon would soon announce a 17mm TS-E of exceptional quality, I would not have bought the D700 and Nikkor lens.
Like many of us, I'm a victim of the 'want now' syndrome.
Nevertheless, the D700 still retains some advantages over any Canon, such as, up to 9 frames exposure autobracketing, and full autobracketing of ISO in manual mode.
