2 minute video - shows the new interface and interestingly shows a video of GTAIV install, which takes roughly 6.8GB.
So therefore the average 20gb can do two installs and the 60gb can do up to about 8 and the 120gb could do 16 full disk installs.
Looks pretty good actually, its quite intuitive and visually its much easier to find your way without closely inspecting each tab.
Tease.
