The ManiaPlanet Website reveals plans to launch TrackMania2 Stadium, a new environment for NADEO's racing sequel familiar to players of TrackMania Nations Forever. This is coming early next year, and will utilize ManiaPlanet features as well as their improved game engine. This site offers details, media, and beta signups. ManiaPlanet News also announces TrackMania² Valley, a further continuation of the racing sequel that began with TrackMania² Canyon, saying this is also due for Windows early next year (thanks Frans). A TrackMania 2 Valley sub-site is online, and they offer some screenshots, a launch trailer, and the following fairly brief explanation:

Some of you have waited for it for a while, and we’re now happy to announce the coming of TrackMania² Valley in ManiaPlanet in 2013!

This time, no canyon on the horizon, but a more bucolic setting where crazy drivers will race through mud roads as well as highways. The coming of a new environment of course means a net set of blocks for the editor, but also a brand new gameplay for the driving experience.
