The BlackBerry R10 hasn't been announced yet, but still has made an appearance on camera that too in red. Its the third member of the BlackBerry 10 devices, namely the BlackBerry Z10 and the Q10. This will be an mid-level QWERTY BlackBerry 10 device to be launched in Q3 2013 for those people who can't afford the high-end Q10 and still want the QWERTY BlackBerry experience.
If you look closely their's a white BlackBerry R10 which leaked earlier, therefore it seems that BlackBerry is aiming for the youth to grab the R10 and quite possibly it will be available in several color choices unlike the Q10 and Z10.
