Looking forward to this - as others have mentioned - the few things that would really sell this to me as a good game is a few more unique faces, especially for NH players. Also as others mentioned, passing got mental, especially when they would pass backwards regardless of which way the player was facing, so a player runs right, gets tackled and then does an amazing skip pass left in a way that is virtually impossible.
I'd also like to see some of the faces they've already made kept, so just because Rokocoko now plays in the Top 14, I'd be gutten to lose his face. More unique high quality faces the better in my opinion! - maybe just cause I lack an imagination and have a hard time seeing the players as their some-what likenesses. Really looking forward to this.
EDIT: Also, I'd love to see the goal kicking system a bit closer to HB's Rugby 08. It seemed a little more tricky but you had more control of where exactly the ball would go, rather than 'if you get it in the red, it'll go where you aim it'. Anyway - even without this but the other features, I'd buy it.
