This web site allows you to compare cell phone screen sizes.
Phone Size - Phone size comparison made easy!

By way of comparison:
The current Phone has a 3.5 inch touch screen.
The Q20 will have a 3.5 inch touch screen (which should work like the Q10 interface) plus a trackpad plus a keyboard.

Unless I'm missing something- based purely on size- the phone has got to be bigger then the Q10 or have a slide out keyboard.

It will surely be bigger than the Q10. How much bigger is the question!

Either a larger phone or I guess they could go with a Torch design.
That would give a smaller foot print while still adding a keyboard & trackpad.
