The October 20 release date for Armored Core V has just been pushed back to January 2012. It seems that the compay is using data gathered from a recent online closed beta test of the game, From Software received feedback from players that they're working to implement in the final game, says Siliconera. It's always nice to hear that sort of thing.
Namco Bandai is scheduled publish Armored Core V in North America and Europe. The original plan was to release the title on PlayStation 3 and Xbox 360 in early 2012. I wonder if this push back for the Japanese version will change the US release date. Probably.
