Because there's no reason for snake not being in the next SSb
We know there're no Mgs in the Wii or WiiU
But there is a Mgs Game in the 3Ds
this is the same situation where the GC got a remake of MGS for the PSX
and the 3Ds got a Remake of MGS for the PS2
Plus Kojima and the Fans want Snake in the game , we're not fanboys that hate everything no-Nintendo , like you Sakurai.
