Wow, I'm a happy camper....
Even though this thread is a bit old, I just ordered a 2011 F150 XLT on the X-Plan on Friday. When I configured the truck on Build&Price, it doesn't show that SelectShift is included (e.g. compared to FX4). However, I just checked the computer printout of my vehicle order from the dealer, and it says "Select Shift'. I'm not sure when/where I'll use it, but I'm glad to have it, and now I know that it will be on the steering wheel column.
