In an interview with G4TV, Microsoft's Aaron Greenberg had quite a lot to say about the Xbox 360's performance in 2008 as well as what's in store for the future. Greenberg began by trumpeting the 2008 numbers that were released last week, also noting high sales for Gears of War 2, Call of Duty: World at War and Left 4 Dead. He then clarified that the Xbox 360 has at least a 1 million unit lead over the PS3 in Europe (by install base, not sales). When asked about the runaway success of the Wii, Greenberg stated that the two machines offered different experiences and that he saw no reason why both couldn't successful. "I look at retail outlets and car companies and airlines... you know there's more than one," said Greenberg, adding, "I think what we're finding is that there are two platforms that are clearly having success." Greenberg also reiterated his belief that Sony will have to reduce the price of the PS3 "sooner, rather than later" if the company wishes to remain competitive.

Perhaps most tantalizingly, Greenberg spoke to Microsofts still nebulous lineup for 2009. He noted that while 2009 is "a big year for Halo fans" thanks to Halo Wars and Halo 3: ODST, Microsoft still has plenty up its digital sleeve. Greenberg said that Microsoft prefers to "under promise and over deliver," explaining that the company likes to save announcements until a product is close to launch. He cites the NXE as an example, saying that the company kept it under wraps -- well, mostly -- until E3 2008, which preceded the November launch in the same year.

And before you ask, no, he didn't drop any hints as to what said projects might be. Our guess: Alan Wake and Duke Nukem Forever will both launch this year exclusively on Xbox 360 ... on the same day.
