Microsoft could have an XBLA version - or even sequel - of classic fighting game Killer Instinct in the works, if a post on PlayXBLA is anything to go by.
The PlayXBLA site, which is an official Microsoft creation dedicated to Xbox Live Arcade titles, has posted a rather cryptic update pointing out that Microsoft has renewed the the Killer Instinct trademark, which is sufficiently out of character to count as a tease.
"With all due respect to our friends in the media who like to frequent trademark sites," the message reads, "We thought we'd break this one ourselves. :) Our legal eagles have authorized us to say: "We have either renewed or refiled a trademark application in various jurisdictions."
There's no reason to point this out unless there's something afoot. There will be many who will want this to be the long-demanded announcement of a Killer Instinct sequel, which is something that people still hassle Rare about - but it's previously been said that while Rare wanted to make Killer Instinct 3, Microsoft wasn't interested. The trademark renewal is more likely to indicate a HD re-release in the style of Perfect Dark or Banjo-Tooie. Both of those titles, like Killer Instinct, had their heyday on vintage Nintendo hardware, although Killer Instinct actually began life in the arcade - they were both brought to XBLA by 4J Studios, too, which is currently working on the still-not-updated-yet-please-stop-asking Minecraft XBLA.
Microsoft has previously said that the game "has a home on XBLA" so it's not entirely unexpected. Maybe Microsoft decided that it wanted to get in on the fighting game glut we've had lately, with the likes of Dead or Alive 5, Tekken Tag Tournament and Persona 4 Arena all arriving around now following Mortal Kombat and a billion flavours of Street Fighter last year. Killer Instinct has the edge on all of them through features such as those in the video below.
