I'm keeping a very close eye on this.
I was a die hard BB user for years, and my final device was the 9930 which I absolutely loved. However, the need for LTE data finally got me and pushed me to the Android world. I went through multiple phones in a few years looking for one I liked (Droid 2, Droid 3, Droid 4, RAZR MAXX, RAZR HD MAXX, S4, G3, and G4). When I got the G3, I finally became happy with Android and that has continued on the G4. However, I do miss my keyboard.
If BB can pull off decent hardware specs and a decent screen and camera, then this will be a top contender for my next phone. It would be the best of both worlds.
