A little of both, as I understand it.
I guess I am thankful I played this on PC, the load times were not anywhere near as bad as they sound on the 360.
I dunno, they seem to add alot of "flavor" to their Haruhi subs. I don't think this has anything to do with accuracy, however. Plus, the quality could be better.
The reports I've read had the PS motion controller tech beyond what even Nintendo was doing, but they should not have shown it at that stage of development, and the demonstration was clearly a rushed, last minute addition.
