I think it has the potential to increase sales fairly substantially if marketed properly. Not 'zomg revolutionary kill PS3 start competing with Wii', but it could increase its' week-to-week lead over the PS3, especially increasing sales in Japan due to the user-friendliness and the big-headed avatars.
Could I trouble you for some maple syrup to go with the plate of roffles you just served up?
