It already got asked here but it seems like nobody answered, and I think site discussions is the right place to talk about it.

Will it be splited into another page or will they just be on here as news envis?

I have no knowledge about what will be done, but it also seems a bit early to say.

There's still some questions. Will tracks work between Turbo and TM2? If yes, then it might make sense to have them here.

If not, then maybe a new sub-site would be in order. It is a new game after all, and not part of ManiaPlanet/TM2. Either way, it's not my call. Just offering my opinion as a fellow user here.

Yeah, I agree with eyebo. Even if the tracks can't be played together I doubt they will make a whole new site for it, it will probably just be just like when SM was added.

It depends on how the game develops. We know about nothing yet regarding those details.
