Rifter, de planet tribes a mailé Sierra pour en savoir plus sur le suivi des mods, des patchs et d’une éventuelle extention :

After this patch, we’d like to give the game a chance to stand on its own and see how it does. At this point the code is stable and the balance is pretty tight, so it’s time to let gamers focus on developing skill and strategies ased on the latest and greatest. As far as MOD support, we always have upported that community and will continue to do so. There are great resources on www.tribes2centraldownload.com for modders. There are a number of super-good mods that have already come out for Tribes 2, and we expect work begin on many more once the game is all locked down.
No news on the expansion pack at this time.
