There appears to be considerable planning taking place as to how a user will access Windows. Right off the bat, one of my favorites is the following prototype which shows a user logging in via facial recognition! Basically, you enroll your face, then all you should have to do from that point forward is sit down, have your webcam get a look at you and then log you in based on facial recognition:

The following slide details other considerations for Windows 8 where identity is concerned. Namely, user accounts will still be the primary method of accessing Windows for individuals, fast user switching is a continued focus, and most notably, Windows accounts could be connected to the cloud which would allow for roaming settings/preferences between PCs and devices and PCs to log on to websites on the users behalf all marking an evolution of Windows identity from being machine-centric to user-centric.
