After a full QWERTY keypad and SureType, expect some radical new innovations in keyboards on newer BlackBerry devices from RIM.
If these patent filings actually make it into the devices, you'll have a BlackBerry with a rotatable keyboard that gives you a more standard numeric keypad for phone usage and, when rotated, a more convenient QWERTY keypad for full text input.
Another idea is a flip phone which also has dual-keys. In normal orientation, the number keys are vertical ovals, but when used in a landscape mode, they serve as a full QWERTY keypad. Nothing too fancy here, but the idea of a clamshell BlackBerry is worth its weight!
The third concept doesn't seem too impressive. It's a rotating thing again, but the entire back part of the phone rotates to reveal a keypad on both sides of the phone. I think Nokia's E70 form factor is much better than this one.
No idea if any of these concepts will actually make it into any BlackBerry devices, but it's interesting to see what RIM has been thinking of.
