I personally think that since the merger with Enix there has been a shocking decline in the quality of square franchises particularrly the once great Final Fantasy. However to offer Blizzard's lineup in exchange really doesn't sound agreeable to me. They are two entirely different formulars. FF main series is turnbased rather than Blizzard's action based. They really aren't the same kind of games. I'd like to see Square pawn off the series to another developer at this point, because it's starting to look like the new Simpson's too me.
