Can All Stars sell MILLIONS of copies?

[OneHappyGamer:)]

Considering the very large core gamer fanbase on the PS3, combined with the PSVita sales (although small) i think this game can manage 6 million or more LTD. it all depends on how Sony advertises this though.
I'm definitely getting it. I played the Beta on my PS3, although i don't feel that it is as good as SSBB, but still very fun non the less. characters feel very unbalanced imo :p
