The next generation system of Microsoft. First came the X-box, then the X-box 360 (event though the system isn't a circle) and so it is assumed by most people that next will be the X-box 720. It is a reasonable name for the next gen. of X-box.
Sometimes used as a joke when asked if going to buy a 360.
The next generation of video games is here. The X-Box 360 is Microsoft's newest contribution to the world of video games. This thing looks to be even a hell of a lot better than the already amazing X-Box. Set to release sometime in 2006.
Sometime in the near future:
Bill: Hey, wanna play my old X-Box?
Tom: Fuck no, lets go play my new X-Box 360. It kicks ass!
A games console that takes 4 delivery men to deliver to your house because it is so big and heavy. Also you have to build an extention on your home for it to fit in.
''I wanna play on my x-box whilst i recover from my hernia operation but i have no house to play it in''
