Speaking to Next Gen, Microsoft's Aaron Greenberg laid down some lofty goals for our favorite console. While most of the interview focuses on Microsoft's new family friendly initiative, Greenberg notes that he expects the console to have a very impressive holiday, saying that the Xbox 360 will have several top selling games. "Just this one holiday we anticipate that we'll have at least seven titles that will each sell over a million units each," said Greenberg. Seven million-sellers? That's a bold prediction to be sure. While he doesn't elaborate on which games will get the honor, we'll venture a few guesses. In no particular order: Assassin's Creed, Rock Band, Guitar Hero III, Orange Box, Call of Duty 4, Mass Effect, and oh ... heck, Halo 3 will sell at least another million over the holidays. Anyone else care to make some guesses, or perhaps, a wager?
