Not much to this other than the pictures, but it’s something. Images have popped up around the web showing an unnamed, previously-unknown slider device sporting a big blackberry-style keyboard. The trademark glowing red Droid eye is visible in one of the pictures, and the Motorola logo is visible in another (first and second images below, respectively).
Engadget is reporting this thing is real (rather than a cheap Chinese knock-off of some sort), and their track record is pretty good. Thus, chances are good that these are legitimate shots.
