Well I've been playing this the last couple of days. Awesome, but man has it got issues. I can't help but feel it could be so much better with a more alive city. And the bike physics seems completely random - I go head on into a car and glitch past and and continue at full speed, while I hit a 1m high wooden post and crash.
Combat is really awesome though, I love that they didnt go the obvious route of full wiimote stuff, the flicking for finishers is awesome, as are the wrestling moves.
