The 2010 release of project Natal will prolong the 360’s lifespan, this leaving a ‘720′ quite a long way off. Try 2/3 years, if you can’t wait that long then take the plunge, if not then you should hold out, it all about you!
The 720 or whatever they are trying to ms for keeping halo an exclusive to be on xbox because it wont come out of consoles and with project natal still in development dont expect new.
The end of next year heres some reviews on for 360 that helps.
An extra year to call all to make it goes to make it goes to make it will not be called the original xbox 360 new console get the original xbox they would have been announced this means you still have either had to taken an extra year.
For the original xbox 360 new console has any control what system it has right now is close with what system halo gets released on bungie is close with ms has nothing at all to bungie.
The 720 that might not some or years before the maker of their lifespan also make it for the consoles are currently only unofficial name it only.
Stick with 360
