When is Super Smash Bros. Brawl 2 going to come out

There will never be a "Super Smash Bros Brawl 2", however it is possible that in the future Nintendo may make a fourth game in the series.

SSB Games:
Super Smash Bros (N64)
Super Smash Bros Melee (GCN)
Super Smash Bros Brawl (Wii)

The next game will be Super Smash Bros Dojo and I don't know what game system it will be for since more will be made (but I'm guessing the new Xbox)
