The saga of the latest Guilty Gear console release is complicated. To make a long story short, fans have been waiting a very long time for the newest console iteration, Guilty Gear XX Accent Core Plus, to be updated into the arcade version, Guilty Gear XX Accent Core Plus R.
Controversy arose when Arc System Works was accused of re-selling the Plus R version on the Vita months ago, before giving out any confirmation of the promised free update for people who already bought the console version. Well, now we have confirmation -- the PS3 is getting the update this month, with the 360 to follow at some point.
To re-iterate, this update will be free, so if you own the console game already, take advantage of it!
