Making to-do and WIP lists only get people hyped and constantly asking for stuff that may take months to be included in the game.
Sure it's cool to know what they're working on or planning to do*, but the annoyance of people starting a new topic every 5 minutes asking when feature X will be avaliable beats it.
*The only thing we know is that they plan to implement Wipeout-like environments. I don't think it will be released too soon, it takes alot of work.
Correct me if I'm wrong and there are more stuff known to be in the works. People that ask when features will be avaliable don't read second posts if they aren't on their topics anyway, so we can talk about those.

(wonders about making a secret noob/fanboy-proof topic...)
