Will they make the right games? They've been hiring devs and buying devs for years, but so far they haven't made many other franchises like halo and forza
It takes time to develop new games from scratch, especially good ones. So it's understandable they've been quiet so far, preferring to develop in silence without overbearing pressure.
I think we'll going to see at E3 what the state of their Next gen will be, at least early on.
