Microsoft games boss Aaron Greenberg's confirmed both Crackdown 2 and Alan Wake for a first-half 2010 release, speaking in the latest Major Nelson podcast.
"Starting in January we have like a triple A exclusive title pretty much every month for the first half of the year. You've got Mass Effect 2, you've got Splinter Cell, you've got Alan Wake, you've got Crackdown 2," said the exec.
"You've got things like Fable 3 and Halo: Reach and coming later that year. Those are just the exclusives."
Listen at about 31.50. He added: "2010 will be a bigger year that 2009: no doubt."
No specific dates have been given for Remedy's opus or Ruffian's inaugural, but you probably wouldn't be too stupid to be thinking "May-ish".
