The Passport has form, you cannot argue with that.
I actually think it is likely to happen if the Priv sells well.
I don't think Blackberry would ever do another form factor like the Passport. They have done a 'Classic' style android device. "Mercury" "DTEK70"
I think the Passport wasn't very practical for the average consumer and for watching videos, the black bars were not appealing. I loved the idea of #WorkWide and the first day it was available in stores i went to get my hands on one. I just felt the keyboard was too close to the bottom and i missed the 4 rows. Ive only ever purchased Keyboard devices from Blackberry and the Passport was the only one i wasn't a huge fan of. The keys were lovely though. Did it look great? Absolutely

John Chen even dared a news reporter to try and bend it. It was so well made. Lots of potential and was supposed to be a 'Family of devices'. But they cancelled the others.
Coming from previous BB OS 7 devices, moving to a Q5, then Classic and now PRIV.
