We saw the poster and possible lenses for Canon's EOS 7D yesterday, and now it looks like the floodgates are open. A photography forum has most of the details you'll need, except the exact price and release date.
It'll have a 18MP sensor (which is kind of overkill), dual DIGIC 4 processors, ISO from 100 to 6400 (and some crazy 12800 mode), a 3-inch LCD in addition to the 100 per cent coverage viewfinder and of course HD video capabilities like its siblings. It looks like it'll compete most directly with the king of prosumer DSLRs, the Nikon D300s. Past rumours have suggested it'll cost around $US2700, but we'll wait and see: We wouldn't be surprised if it was actually a lot less. [Engadget]
