I definitely say checkpoint save, quicksave and save anywhere. Basically Half Life 2's save system. The problem with console games historically was that there was not enough flash memory to have a snapshot save anywhere, and its not helping that the 360 dropped the hard drive in their cheaper model, and asked the developers to program for the lowest denominator. I'm hoping that developers would provide the people with hard drives the ability to save anywhere, and everybody else a check point save. If you want to make your game challenging, try to rely on gameplay mechanics rather than forcing people to repeat the same sequence 200 times.

As far as Rewind goes, it is a brilliant idea to counter saves anywheres in SOT, but I can tell you from an engineering perspective, it's a lot more work than just providing a single save anywhere.
