Can they now?

http://www.apple.com/displays/ still says that only MBP and iMac can do it.

There's a thread on the AnandTech forums claiming it is possible: http://forums.anandtech.com/showthread.php?t=2251899

That picture looks like a MBP though?

Yes, the 13" can, other places say it can.

Macbook Air (2012 at least) with the dual link DVI adapter can. Source: I use it with my MBA.

It's really funky. Intel HD 4000 has the ability to drive this high of a resolution but only over DisplayPort, HD4K+HDMI or HD4K+DUAL_DVI is a no-go, so be warned. If you have integrated graphics, you will need an external card (unless your mobo has DisplayPort out). I've got an Nvidia now driving it over Dual link DVI.
