Oops. Seems like someone at Microsoft has inadvertently let the beefy space marine-shaped cat of the bag. Earlier today an update on Xbox Live revealed the next game would conclude Marcus Fenix's trilogy, with a release date set for April 2011. While GamesRadar is sympathetic to the dogsbody who's no doubt getting his pink slip for the blunder as they type, GamesRadar is more interested in talking about what they want from the newly confirmed sequel. Which is what GamesRadar about to do in word-based form.
