The problem with it though, is the BlackBerry is saying nothing about it and are letting the rumors and leaks do all the talking. Now, yet another piece of info has apparently leaked out and this time around it's the alleged retail demo for BlackBerry Blend. Have a look for yourself. If you've not been following the rumors, the video will explain what we're looking at here. Although I'm not sure what the hold up is on announcing this, the whole 'Mobile First' idea BlackBerry has mentioned surely has something to do with it.
