I think you kind of hit the problem, but kind of missed it as well. It's more premature announcement syndrome, where a game is announced only slightly after some concept art and ideas can be crammed into a trailer, then potential development time is ignored. It's not like these guys are fanfic writers bouncing from idea to idea but never finishing everything. These are "ahr-teets" (artits) that won't let a development schedule get in the way of their ideal work. Some of the trailer excess and pointlessness is our own fault. Fans just expect something at both E3 and TGS, even if there's nothing new to see, but I don't think anyone's sitting on their laurels here.
Admittedly, SE does need some focus, and the best way to do that is to remove the millstone of FFXIV from their neck. I mean, I could start at the folley of continuing to try and leech the WoW crowd, or the general stupidity at creating a game that would ultimatly compete with one of your other games (XI), but there's an extra credits video about MMOs around here that makes the point better. Rather, even if you could ignore the bad idea it was in the first place, they still botched it, and botched it bad. Now they're spending time and resources trying to make the unplayable playble that could better be served on other projects like versus XIII. I admit, I like the influx of PSN and DS releases of older games to keep cash flow going and want it to continue, but lloking forward, the tallent could be spent a lot better.
