Rogers is claiming to have two new devices coming down the pipe.

One is the 7100 replacement (8100)
and other is a QWERTY model similar to the 8100.

both apparently going to include the trackball.

An aside: i would suspect the QWERTY model to be an '8700' alternative, maybe even an upgraded version, but that's just my opinion. A slight upgrade, not a major upgrade. The CPU/basic platform would remain the same, they will just add the memory, possibly the camera, and the trackball.

Rogers claims late Q3 early Q4 for release.
