That was unexpected. It appears that the Killer Instinct trademark has been “either renewed or refiled” by Microsoft, who purchased Rareware some time ago. KI, you may remember, is the fighting game best known for one thing:
Sweet, sweet combo breakers. This is literally the only news we have about the situation, as Xbox Live Arcade chose to break the news itself, rather than let the media stumble across the filings.
