Either CreativeVideo in the UK has let the cat out of the bag, or they are making things up, but they have a product info page up for upcoming Sony "Cinema" camera (think of it as a large-chip i.e. 35mm video camera.)
They give it a name; the PMW-EX35, launch date; 15th February, and a price; £12,500.
At that price, you're talking RED prices (i.e. $19,000) not Panasonic AG-AF100 prices.
It also seems a little odd that they'd have this, though Sony is supposed to be having an event later this month to reveal more, so maybe, just maybe...
