With regards to the game, apparently it's in need of plenty of polish before release - probably as you'd expect. The actual swordfighting bits aren't as free as you'd imagine: there are pre-determined strokes/swings you need to make (ie: the sword isn't mapped to your every move). Also, the movement whilst with the gun isn't particularly 'free' either.
This comes from IGN, but I would expect (as they stressed) that these are easily fixable problems.
It looks great, and I hope it's a launch title along with Metroid, Mario and Zelda
(I'm gonna be poor come release...)
