Fujifilm had several X-Pro 1 cameras on their booth at CES. I could not take any sample photos with those units, but they were fully operational. One of the representatives confirmed to me that the new X-Trans CMOS sensor is made by Fuji. Nobody could give me details on the pricing, but the general feedback was that it will be very close to Amazon's listings from few days ago. There will be no lens kits for sale, just body only (maybe this is only for the US). The M-mount adapter for the X-Pro 1 will be announced/introduced later in 2012. 
Some of the Fuji X-Pro 1 accessories:
Compared to the Fuji X100, the X-Pro 1 has also a new menu system, larger LCD screen and shutter dial lock button (in addition to all other differences):
