Moon Diver to Release on XBLA on May 4th

If you follow the psn store at all, you may have heard of this neat hack n slash game that was released back at the end of March. Good news for Xbox is the game is coming to XBLA on May 4th! Check out the video posted by Kotaku. I have to say that I am looking forward to this. Only thing is it is likely going to be 1200 MSP since the price on psn is $14.99. Is it just me or does $15 seem to be the norm for downloadable games?
