The Xbox One
doesn't launch for another few months, but you can get your hands on it in a week or two. A few Microsoft stores are opening
and Major Nelson will be there to show off Microsoft's new console.
On September 19, the Microsoft Retail store in Burlington, Massachusetts will have the console available for play between 7:30 pm and 9:00 pm. The next day, the Microsoft Retail store in Boston, Massachusetts will have the Xbox One there as well between 7:30 pm and 9:00 pm.
Two games mentioned that you'l be able to play are Forza 5 Motorsport and Killer Instinct. One cool thing about the Killer Instinct demo is that it will be in the old arcade cabinet.
If you're interested in going, just show up and have some fun.
