If this is true, Canon would be stupid to not have another camera to satisfy people who're looking at the $5k - $7k range.
It would truly be stupid, Sony will grab the market easily. Also don't sleep on Panasonic. That AF100 is due for an upgrade.
I agree with you, but I think there may be a bit of a turf war going on between their camcorders and CINEMA EOS team. A $5K 4K cinema DSLR would probably cause the Canon camcorder guys to draw their Katana blades.
