Given the impressive list of tune-ups, I'm hoping that some improvements will be made to mapmaking -- or perchance, even "modding", which was never really supported aside from third-party hacks. On the low end, support for mp3, Vorbis, or some other compressed audio format for custom sounds would be nice instead of .wav, but if they aimed higher they could rejuvenate a player-generated content community for years to come.
