I doubt there will be a 2013 cinema display.....but will be a new thunderbolt display based on new iMac .
TBD is bad choice for me, no chance to connect xbox
It is likely not in Apple's strategic plans to help out MS's Xbox. Maybe the much rumored Apple TVs (late 2012 or 2014?) will offer a solution.
I believe that support for other then one and only apple computer is not supporting xbox.
Actually, it's a lot more than one of Apple's computers that supports Thunderbolt- all of them (excluding Mac Pro) support Thunderbolt.
