Most likely that both RT 2 and Pro 2 will have the same WiFi adapter and about what I can find, the components are the same as the 1st generation (Marvell).
Nobody, anywhere will list the components except the processor.
The docking station looks like it works with both and both tablets have the connection port on the right side and the video port on the left side.
The keyboards are backlit for both the touch and type covers plus the 3rd cover which is also a battery pack will also have a backlit keyboard. Those keyboards are backward compatible with the 1st generation models.
They also have a wireless adapter for the keyboards so that they can operate detached from the tablet.
Some of these accessories, though, won't be available until early 2014.
I have a RT that 3 weeks ago started working 100% after I swapped out the touch cover for a type cover. A little strange, but not going to complain. I think I will just keep it. May get the Pro 2, but don't really need it for anything.
