The PlayStation Vita port of Rayman Legends launched with missing content due to a longer-than-expected development time. Specifically, the console versions' Invasion mode wasn't included on the platform and as annoying as its absence was, Ubisoft at least promised to patch it in via a future update. That update has since been dated for November 26, 2013.
Good. There are also Xbox One and PlayStation 4 versions of Legends in the works but, frankly, I think PS Vita is where it's at for this game. Glad to see it move toward feature parity.
