Zipper Interactive community manager Jeremy Dunham has said the developer will be releasing information on the next MAG patch very soon.
Posting on the game's official forums, he had this to say:
“Info on our next patch will be coming next week (but not all of it -- it's so large that it will take multiple updates to tell you about it) and info on our bigger DLC will be after that (before E3).”
SOCOM 4's announcement caused uproar in March, with fans concerned Zipper would no longer support the 250-man shooter.
Zipper has always denied that it will stop updating MAG, saying it will continue to support the game for the foreseeable future.
MAG was released late last year.
