That might be a trick in the bag though... not teasing ~not likely either; but not impossible. They've said the would like to if they can get the console manufacturers to allow it. It'd be quite a coup to get M$ on board and not Sony ~or vice versa; for who would buy for the console that refused to allow it?
But they are rightly afraid of bugs, I'm sure. Bad mods could make the console seem unstable. Does no one else think that the paid mods initiative, was to ultimately include [pull over] the consoles too?
My guess is that FO4 already has the support built in; or did.
