Was looking up the Armada line and in this PDF of the 618 they show a blurry pad on page 2 that looks like it has had some stuff covered or blacked out to keep it plain or hidden. If you look it looks like they blacked out 3 things at the bottom. Could this be a picture of the new Blackberry Tablet with BB Menu key (left bottom), the trackpad (center), and the return key (right bottom) blacked out? It's a reach, but it doesn't look like any tablet that would run android.
Here's a different one from the home page. My thinking is that RIM didn't have the time to crash a tablet program, so it will be closer to reference design.
The fuzzy tablet in the pdf is a mock-up image. It is just a place-holder for what they are talking about. As the figure caption says: "Platform Reference Design". The only way that could be similar to the Blackpad is if RIM was mentioned (it wasn't).
