Plenty of us "read up" on whatever info was released by ATI, and the following is the kind of stuff that was released.

On the official release notes for the Catalyst 9.12--

The ATI Catalyst 9.12 hotfix release provides ATI CrossFireX support on Eyefinity configurations, allowing users to take advantage of their additional GPUs for increased gaming performance when driving high resolution Eyefinity display groups

Supported on the ATI Radeon HD 5970 Series, ATI Radeon HD 5800 Series, and ATI Radeon HD 5700 Series

5970 CFX is clearly included in their release notes as being supported.

From review sites prior to the release of the 9.12 Cat:

The drivers that the 5970 will be shipping with enable Crossfire Eyefinity support on the 5970 for 22 games - currently AMD is using whitelisting and is enabling games on a case-by-case basis.

The reason why the Radeon HD 5970 supports Eyefinity now is because it was easier to get working first. The onboard PLX PCIe chip on the video card gives AMD a known set of PCI Express lanes to work with, and knowing that the configuration will never change they were able to get Eyefinity working with this configuration first. A future driver down the road (not Catalyst 9.12, so think 2010 for support) will enable CrossFire on Eyefinity for all other configurations.

So right out of the gate, ATI was pimping the 5970 as the card to go with for Eyefinity while promises were made that eventually it would work for "all other configurations" according to some of the review sites. This was over 6 months ago, now.

If this were not the case, then ATI should have made that very clear right up front to dispel any confusion and keep many people like myself from wasting 700$ on an extra 5970 and 400$ for an additional two LCDs.

But no-- it's even included in their release notes with the Catalyst 9.12 that IT WORKS with 5970 CFX, yet it doesn't. Out of 10-15 users over on Rage3D, not one person has reported that this is working in any title. And not a single beta tester has proven that CFX works on 5970. No one can.. because it simply doesn't work.
