I just got used to Kindle as a name for eBook readers, but Nook? According to the WSJ the Barnes & Noble eBook reader will be called Nook and have a color touch-screen.
The B&N Nook will have the same price as the Amazon Kindle ($259).

The WSJ got the above information from an Ad that will appear in the New York Times Book Review on Sunday.
I would be surprised if the B&N Nook has a color screen. Plastic Logic said that they are not ready to ship it this year. It is more likely that it will be a dual screen device.
Just yesterday a start-up called Spring Design announced Alex, a dual screen Android powered eBook reader. Alex is not the B&N reader, but might look very similar based on the earlier leaked alleged B&N eBook reader photos.
