Which will sell more hardware Fable 2 or Little big planet?

[Skeeuk]

i dont think fable 2 to be a system seller, halo 3 wasnt, gta4 wasnt, i see no reason why fable 2 will do it.

lbp will on the other hand be a system seller, but i feel its a kind of title that will have very good legs and will keep selling.
