I'm sure the aliasing and moire issue is very easy to fix, as Panasonic and Sony have pretty much fixed it. Canon probably could have easily fixed it in the digic 4 DSLRs, but were too busy milking their customers to solve such a basic, fundamental problem.
I think it would be cool if it were a mirrorless (like the Sonys and Panasonics), and used an electronic adaptor for EOS lenses since they have a longer flange length. This would make the most sense, since putting a mirror in a video camera is dumb as heck. That way (like the Sonys and Pannys) any lens could be adopted, including PL mount.
And obviously, the ability to adopt EOS lenses is a HUGE sell since all the competitors like RED, Sony and Panny are having EOS electronic adapters made for it, it's obviously there a huge market to use EOS lenses on video cameras. Obviously it's not as ideal as a cine type lenses, but it's a very affordable solution that can get great results.
I hope they keep it small, smaller than the Sony FS 100 and the Panny AG1001
