We're still sitting in the press Q&A with RIM CEO Thorsten Heins at BlackBerry World, but just to clarify any misinformation out there that RIM may potentially not build physical keyboards for BlackBerry 10, Heins said:
"We want the typing experience on BlackBerry to be the BEST in the World.. both touchscreen and physical keyboard"
So that's that. Confirmed. There will be a physical keyboard option in the BlackBerry 10 portfolio. The first BlackBerry 10 phone will be full touchscreen, but there will be physical keyboard BlackBerry 10 phones.
