BlackBerry’s comeback efforts are now fully underway, but the BlackBerry Z10 and BlackBerry Q10 are just the beginning. According to a new report from Digitimes, BlackBerry still plans to launch as many as four additional BlackBerry 10 smartphones before 2013 is over. We already know the recently announced BlackBerry Q5 will be among the new handsets BlackBerry is prepping for the second half of 2013, and recent rumors suggest the BlackBerry A10 will launch in November as a sequel to the full-touch Z10. That still leaves one to two additional BlackBerry phones that will launch later this year according to Digitimes’ unnamed supply chain sources, though no details on the mysterious handsets were reported.
