XSEED is also releasing Earth Defense Force 2 on Vita in the fall. See thread: http://www.neogaf.com/forum/showthread.php?t=1053962
[Platform: PS4™ system; Release: Fall 2015]
The wild sci-fi action of the Earth Defense Force series comes to the PS4™ system for the first time in this complete reimagining of Earth Defense Force 2025, now with silky smooth framerates, beefed-up graphics, and over 50% new content. After selecting from one of four unique playable classes and customizing their weapons, players will lead NPC troops into city-wide battles against hordes of seemingly endless giant bugs, robots, and other colossal enemies. Two players can enjoy local co-op and versus modes, while online co-op supports up to four players to increase the odds against this massive alien threat.
Both games were playable at E3!
