Looks like we will have a bunch of new things to play with.

Catalyst v8.3 driver suite will officially support three and four GPU CrossFireX configurations. You may have heard some scuttlebutt over the last few weeks stating that CrossFire works with some mismatched GPUs as well, which is actually the case. AMD's new Catalyst v8.3 drivers will let users match up Radeon HD 3870 X2 cards, with standard 3870s and even the 3850 - basically any RV670 / R680 combo will work. This is interesting because it adds some level of flexibility to end-users looking to take advantage of a multi-GPU setup. Three-way CrossFireX configuration can consist of three Radeon HD 3870 cards, or a single 3870 X2 and single 3870, for example, or any other combo of HD 3800 series cards. And four-way CrossFireX can be achieved with a pair of Radeon 3870 X2 cards, or four standard 3870s, etc. We should note, however, that three and four-GPU CrossFireX is only supported under Windows Vista and only with DirectX 9 and some DirectX 10 titles at this time. Full Support for DirectX 10 (with four GPU scaling) and OpenGL will come at a later time, although Call of Juarez happens to be one DX10 game that does scale currently with four GPUs. Also note, two card CrossFire is obviously still supported in XP; it's just the three and four GPU setups that are exclusive to Vista.
someone just asked about thatHybrid CrossFire will also be officially supported in the Catalyst v8.3 release. As we outlined in our initial coverage of the technology, Hybrid CrossFire gives users the ability to pair an RS780G IGP with a discreet Radeon HD 3400 series graphics card for increased performance or low-power operation
Catalyst v8.3 drivers brings added flexibility to multi-monitor users under Windows Vista. In the past, users were required to disable CrossFire to watch certain types of video or to utilize additional monitors. But with the Catalyst v8.3 release, that is no longer the case. With cards from the X1800 series on up to today?s HD 3000 series, utilizing an extended desktop in a multi-monitor configuration does not require CrossFire to be disabled.
Also new to the Catalyst v8.3 release is official support at the software level for DirectX 10.1 and the hardware tessellator built into the RV670 GPU. Although support for DX10.1 and hardware tessellation was available in hardware, the software mechanisms necessary to expose the functionality had not been incorporated into ATI?s drivers until now.
The Catalyst v8.3 driver suite will also feature a couple of new anti-aliasing modes. New to Catalyst v8.3 will be support for anti-aliasing in Unreal Engine 3 powered games and new edge-detection algorithms that work in conjunction with the Super-AA modes available with CrossFireX.

ok can someone dumb it down for me...
in WIndows XP if I try to run my 3870 X2 with a 3870 this would make it "three" cards and from what I read above... in XP this will NOT work (limited to 2 cards only) and would work only in Vista as it support 3 and 4? Or am I reading this wrong.
The X2 and one more card (any card) is considered 3 cards or are they talking about 3 actual PCIe slots?

It says you can do any combination. 2 x 3870x2's, 4 x 3870, 1 x 3870 + 1 x 3870x2, or 3x3870's. So, depending on what configuration you'd need 2,3, or 4 PCIe slots.

can you do 4x3870X2's?
Aye, I can't believe it's taken that long. They've also dragged their heels into getting AA into UT3 based games.Notice the new aspect ratio scaling? That's the biggest news as far as I'm concerned. As said at rage3d, it's at least five years overdue.
