Heck, they could have four games. George K., said Banjo 3 is coming this year, Scribes said Team Viva's next game could come this year too. There's Viva DS that should be bloody out by now and, of course, their XBLA team has been quiet for a year.
And if we're getting really crazy, Chris Seaver hasn't released a game since 2005 and the Perfect Dark team has been working hard on something for almost three years. I expect no less than 17 new games released this year, along with the requisite remakes of the first two Banjo games.
