Curiously I can't seem to find this answered. Other than assumptions and 'comments' that integrated chipsets can't run multiple displays from random sources. Apple doco suggests it can run a 2560*1600 display but no mention of daisy chained Thunderbolt ones.
This isn't a big issue for me as I've just ordered the 11" Ultimate and a single Thunderbolt display but I'd at least like the option later on
