A new Sony ultra portable?

JkOnTheRun.com points to this teaser campaign by Sony, which hints at a new ultra portable from Sony. Based on today’s teaser message ““Is Your Finger really the Gate Keeper?”, it looks like it incorporates touch and it appears to be some sort of slate.

Jk has all the pictures, so check out the teaser and the sketches which might also point to a slide out keyboard. That would be pretty cool. I wonder if this device would qualify as a UMPC?
