Welcome! These forums are definitely the best source of information you can find on the Bronco, anything you could want to know (as well as everyone's opinions on it) is somewhere on this site, so I would just recommend digging around and seeing what you can find.
I don't think so, the F-150 already fills that role, and their new CEO has been pretty vocal about putting new emphasis on commercial trucks as well. It's an important vehicle for them (they seem to be thinking it'll account for 8-10% of their total vehicle sales), but not a tent-pole.
@Dmk08 See this is one thing I'm worried about: if there are like 1,000 people doing Granger, how is that going to impact delivery times? I understand that cars are being built based on reservation number, but I got to imagine there will be a lot of early reservation numbers signing up for Granger.
