I'm in love with my 360. Greatest console ever (and I have been playing since the Atari days) so I would buy a 720 or an add on or whatever it is they are coming out with.
If the xbox tilted it would automatically go to dash board to not scratch the disk
The xbox has a wireless connect built into it which is very powerful
They implement a new dashboard that runs quickly, but is not mandatory to grab so people with the older 360s can keep using the old one without using so much memory
they don't need to make a new system because neither sony, or nintendo is creating a new one, and they are still selling units. But yes, whenever the new xbox comes out I will be buying it.
