Zipper isn't planning on stopping all the support they're giving to MAG anytime soon. The developers have a number of new content coming down the line, most of which will all be free.
One of the biggest requests from the community is for the ability to have all three factions fight on one map and Zipper plans to deliver that later this year. That DLC will be out closer to the end of Summer, early Fall but you can expect a number of other updates before then.
For starters, one of the new features will be "Clan Wars." Clans will be able to challenge other clans in a best of three battle. Challengers will attack first and then roles switch until an overall winner is declared. Clans will also be associated with leaderboards which will give players a chance to back out of a challenge if they see the opposing team is too strong.
Other updates will include "Sabotage" and "Suppression" missions becoming neutral territory based and "Happy Hour" which gives players double XP in their first couple of matches of the day. Expect to see improvements with the visuals, animations, effects and various other tweaks here and there too. Zipper will also be giving users access to beta servers at least once a week where players will get to experience upcoming new treats.
Zipper is planning even more than what I just listed here which just goes to show you how much they love their fans. Be sure to check out our preview of the "Interdiction" DLC coming to MAG on June 22.
