I know the Toybox Speedway hasn't even come out yet, but just in case there's any Avalanche devs reading, the Speedway (and probably Takeover as well) NEEDS to be forward compatible and playable in 4.0. I can live without a tower defense and old playsets in 3.0, but I'm sure losing speedway in 4.0 would be awful! Maybe just release a new version with more tracks
