Will there ever be a Pokemon Stadium 3?

[Mew~]

Yes, there already is, it's called Pokemon Colosseum. There's even a Stadium 4 and 5 called Gale of Darkness and Pokemon Battle Revolution.

This is basically it.

They are all stadium games, just different titles. They all fall under the same category.

Well if we are now going to talk about a stadium 7... I guess I would like a long rpg mode. :)
