Here are some devices that are possibly in the works
The first is a portrait slider to the palm pre or torch and the second one is unique and kinda hard to describe, it incorporates a storable keyboard that is touch enabled like the passport. I hope other companies blatantly copy Blackberry's innovative designs so they don't remain niches.
