Check out this latest End of Nations interview at GamerVision with Trion's Senior Producer, Gary Wagner:

"There’s also persistence in terms of a metagame aspect to the game world as well. You‘ll be given the opportunity to join one of two sides or factions, once you start playing the game. The metagame is these PVP combat instances that actually change the balance of power in the game world. The metagame will actually have certain victory conditions, so, after a month or two after those win conditions are met, we’ll restart the metagame, and at that point you can choose to change sides or factions, or remain with the faction you’re currently affiliated with." - Gary Wagner

Gary and GamerVision also talk about the individuals components of the MMO and RTS genres that are melded into End of Nations, bonuses you get when controlling key territory, base building and customization of units, the meta-game, and a ton of other great info!
