photo nuts: I wonder if the D300 and 7D will just die a natural death. Their replacement will probably be similar to Nikon D7000, if the latter is not already considered the successor to D300. :)
IMO, a 50 MP FF image when cropped down to APS-C size should be a sufficient replacement for those who like the reach of APS-C
But that's just a matter of time, bandwidth and storage, all of which can be solved.
Sdaniella: Rebels are long over due with EOS-1 controls of it bigger dSLR siblings, with thumbwheel controls (lockable) rather than the less effective 4-way Nav buttons or anything menu-driven (even with a touch screen).
Some PowerShots have the thumbwheel, but it's not lockable (for those still using AE modes, and don't want accidental priority adjustments). those who would use M more, it never needs to be locked, unless passed to others for handling.
I very much look forward to the touch screen. I love it on my NEX 5n. I wonder, however, whether it turns off when you have your eye to the OVF? I would hate to have to worry about changing settings in addition to just getting nose grease on the screen... :)
alexst4: ... "wide F2.8 aperture to allow faster shutter speeds for narrow depth of field" ..Man, how narrow do you want it? at 2.8 and 180mm at macro distances it's got to be razor thin. You need more depth of field, not less. I bet it weighs like a brick too. Quality may be good, but the rest is a total overkill for my needs.
A brighter viewfinder is very useful in macro shooting regardless of whether you are stopped down...
