Guardians of Middle-Earth was previously confirmed for December release on PSN, but had nothing solid except "fall" for the Xbox 360 and Xbox LIVE Arcade versions. Well, today Monolith and Warner Bros. confirmed that the upcoming console-exclusive MOBA will be hitting XBLA just one day after the PSN version, on December 5.
Right now, we're assuming the hard (retail) copy will be available on the same day, though given the previous estimate, that might not be the case. We've asked Warner Bros. for clarification. The PS3 and PSN versions are sticking with the December 4 release date, however.
Starting December 4, owners can also grab the game with the Season Pass as a bundle, at least at selected locations. The combined price is $30, while the game by itself is $15 or 1200 Microsoft Points.
Update: We've confirmed with Warner Bros. that the XBLA and Xbox 360 retail editions are both due out the same day.
