Not a "huge" bit of news, but AC4 sold okay on the X360 (around 23k units), despite launching nearly 4 months after the Playstation 3 launch of the same game.
Although few care about the series, this seems to be rather important, as AC4 did create a small boost for X360 hardware. With it now being on the same day (March 8th, next year), this might mean AC5 will hit 50k on the X360 if lucky.
It also seems to signal that From Software is probably going to make most, if not all, of their titles PS3/X360 and launch simultaneously.
Back from the dead, I'm afraid.
