So with ThunderBolt you can daisy chain multiple monitors off a single port?

do you think it would be possible to run more MULTIPLE external monitor off a daisy chain thunderbolt port? if so that would be awesome.

That's specifically stated as possible on Apple's page about the new MBP's:

You can daisy-chain as many as six devices, including your display.

Wait: I misread. No, I don't know if that will be possible. The bandwidth is there, but not sure if the support is available.

It depends on what you're doing with those monitors. Light Peak has only 10 Gb/s of bandwidth, while DisplayPort 1.2 has more than double that, at 21 Gb/s, to support 2,560 1,600 30 bit @120 Hz. What do you think is going to happen, when you plug 3 of those devices, which want 63 Gb/s of bandwidth, into a port that only delivers 10 Gb/s? Crap performance, that's what.

Even if you're 3 monitors are each running at 1080p resolution, they'll require 21 Gb/s. And your LP port is only 10 Gb/s.

So I guess the answer is "it depends". But don't expect good performance with three very high resolution displays.
