[quote name='Scorch']Why 2010? I thought it was 2009, since they alternate years.[/QUOTE]
One thing we do know, is that Infinity Ward has been hiring a lot of people lately.
They let slip, there is a science fiction game on the horizon- which could be COD 6 or a separate title. If this is COD6, then 2009 is possible- if it is not (as many people are saying) then 2010 would be accurate.
