BlackBerry OS 10 roadmap leaked for 2013

Last week we posted a couple of stories related to some BlackBerry OS 10 devices and then RIM itself dropped a bombshell in its earnings call that the BlackBerry OS 10 devices had been delayed till Q1 of 2013, and today BlackBerryOS is reporting that it has got its hands on the entire BlackBerry OS 10 road map for 2013.
According to the report, first RIM will release the promised 4G variant of the PlayBook tablet in Q4 of 2012, then in Q1 of 2013 it will launch the Nevada and London smartphones we have reported about before, but first in Europe then in North America. In Q2/Q3 of 2013, a device called Nashville is reportedly in development along with a 10-inch PlayBook Tablet which has been codenamed BlackForest. Finally, for Q3/Q4 of 2013, RIM has a device called Naples.
Notably, the report states while the new BlackBerry 10 devices will come to Europe first, but their North American debut will also happen in Q1 of 2013. Additionally, devices like the Nashville and Naples could be QWERTY devices as they could be part of the N-series of phones like the Nevada which is supposedly coming in Q1 of 2013.
