Hi, I just came across this review.
BlackBerry PlayBook Test - mit BlackBerry OS 10 - Die besten Tablet PCs im Test - Ranking 2013
(in German, sorry)
They state they tested the playbook with Blackberry 10 and it is rolled out to the playbooks in February (I guess 2013). At least this is not true for my playbook. Quite strangely they spend a lot of lines about the hardware as if it were new. Is this real? I frankly doubt.
