Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on an external display, both at millions of colors
Exactly. I'm not "getting at" anything. I'm just quoting Apple.So what are you getting at? This doesn't mention 2 external displays.

Ok - I am looking for an answer and don't see it there. Thanks though
I posted a similar question in another thread. It makes no sense to me that the new MacBook Airs - with the Intel HD 4000 chipset - are limited to the same one external display and the internal one as last year's models. That limitation was HARDWARE based. The 3000 chipset could not handle more than two simultaneous displays. But the 4000 chipset can. In fact, it was demoed by Intel running on a laptop on this video I posted in the other thread: http://www.youtube.com/watch?v=jOHBkFOyckYhttp://. So I'd like to believe that what you say is true, but until we receive confirmation, we won't know for sure.
To that end, I've emailed a couple of people at Macworld since they were one of the first to figure out the whole you-must-connect-something-between-a-thunderbolt-display-and-a-displayport-display-for-it-to-work. Will certainly report back if I hear anything.

The 3000 chipset in the 13" MBP could support two external displays (powering down the laptop one) but the MBA using the same could not, this is assumed to be due to the difference in the thunderbolt chip used, if that's still the same thunderbolt chip it'll still only support one external display.
Jsolares,
Thank you for taking the time to respond to my posts in both threads. You appear to be spot on.
The 2011 MBP 13 had the 3000 graphics, which could only handle two displays (internal + 1 external) BUT it had a thunderbolt chip - Light Ridge - that had two DisplayPort sinks. Thus, if you connected two external displays to it, it had to pick two of the three (2 external + 1 internal) because it couldn't display all three (again, 3000 graphics limitation). So it picked the two external displays and darkened the internal one. See point 8 here: http://support.apple.com/kb/HT5219?viewlocale=en_US. To quote: "You can connect a second Apple Thunderbolt Display (27-inch) to a 13-inch MacBook Pro, but the built-in display on the MacBook Pro will go dark. This is expected behavior."
Now, the 2011 MacBook Air had a different thunderbolt controller - Eagle Ridge - which had only one DisplayPort sink. So the 2011 MBA was limited in two respects: the 3000 graphics could only support two simultaneous displays and the TB controller could only support one external. Ergo, one internal, one external, period, done, end of story, thank you, good night, drive home safely.
The 2012 MacBook Air, however, has the 4000 graphics, which clearly supports THREE simultaneous displays. So the GRAPHICS could handle, say, two TB displays AND the internal display. But, as you correctly point out, what about the TB controller?
Well, Sandy Bridge ships with 2nd generation TB controllers - Cactus Ridge. But the only differences, as I understand it, between Cactus Ridge and Light / Eagle Ridge is that Cactus Ridge has some more things built into it that were formerly external chips, so they consume more power, but as a system, it consumes less power because those other chips are flat out gone. But what about display capability? Those stayed THE SAME:

Note that Cactus Ridge 2C is the same as Eagle Ridge - only one DP sink.
So, my conclusion: unless Apple put the 4C version of Cactus Ridge into the 2012 MacBook Airs, they are limited to only one external display and will NOT drive two, even in clamshell mode, even though the graphics chipset is more than capable of doing it.
Boy, oh boy I hope I'm wrong, but until someone shows it working, or I hear differently from an authoritative source, I'm gonna go with "no".
I know this isnt exactly on topic, but if the situation is as described above, do we have any options with USB 3?
Pretty interested in this. I'm going to be purchasing a new MBA and was hoping to have a multiple monitor docking station setup in the home office.
Even if it could do it...it would probably be really slow. I hooked up my 13" Macbook Air to a 27" ACD...was NOT happy with system performance. YMMV
Ive been researching this as well...According to iFixit, the 2012 macbook air teardown came up with the DSL3510 L Thunderbolt port (4c)...
http://www.ifixit.com/Teardown/MacBook-Air-13-Inch-Mid-2012-Teardown/9457/2
So according to the charts here:
http://www.tomshardware.com/reviews/thunderbolt-performance-z77a-gd80,3205-3.html
We do indeed have the dual display port ability 4c in the Air vs the older 3310 2C (2011 models).
Pair that with the 4000 graphics card, and I think we have a dual monitor winner. Now, hold your breath Apple doesnt intentionally cripple it!

Not off topic at all. Thunderbolt is still the answer - it's just an expensive answer. Buy this Sonnet external Thunderbolt PCI expansion chassis: http://store1.sonnettech.com/product_info.php?&products_id=402 and put in a mid-range desktop graphics card and you'll be able to hook up at least 3 external monitors (one from the Air, two from the graphics card), plus you'll have more graphics processing capabilities that the Retina MBP. Of course, when you add the price of this to a nicely equipped Air, you'll PAY MORE than a Retina MBP too...
