Blackberry Playbook promo video

The new Blackberry playbook promo video looks good. Its a shame that it has a different os to the phones. Apps for your bb phone wont run on the playbook. Ok thats not good, we will need to develop new apps for Playbook, on the up side however the playbook os does look very good (QNX Neutrino)

Will QNX take over from BB OS 6?
