A spokesperson at RIM has stated:
While this doesn't necessarily mean that the actual phones will be set up to be played with, having official details on how the new OS will work is a definite plus. That may hold off the riots for a little while longer. On top of the reveal of BB10, BB7 seems to be another popular aspect of RIM's revival plan. I'm curious about the new operating system, sure, but those phones could be a long way out. I'm more excited to see how much more I can get out of my BlackBerry Bold 9900. Research in Motion says this is "The year of BlackBerry 10", but the year is young, and we've got a long way to go. Hopefully their determination stays strong and continues for a long time down the road.
