Definitely in terms of immediate consumer effect the b/c announcement would give the best short terms boost to sales. But really, in terms of broader appeal, the new games announced by Sony are more exciting to the gamer base. Does a one week spike in sales and a win on one means of viewing E3 really equal a win? I think that's a hard sell.
