Luckily for AMD, smaller is better in the GPU fabrication business. They announced on Tuesday that they have begun shipping their first 28nm GPUs. These new chips will be showed off in AMD's new Radeon HD 7000 series graphics cards at CES, which is being held in Las Vegas and begins January 10th.
The first unofficial pics of the new 'Tahiti' cards (presumably a HD 7900 series card) are packing 12 GDDR5 chips which suggests that it will have a 384-bit memory bus. The cards are very long and require two 8-pin power cables.

Usually no, but you can Crossfire from the same family and same "branch". ex possible: 6950 6970; 6750 6770; 5850 5830
ex. not possible: 6750 6850; 5870 6870; 4850 6950;
There is a sweet chart provided by AMD with the Xfire compatibility for their cards, broken down to family and "branch", check it out:

Is there enough information leak to theoretically put the 7970 in the database?

I think so. I'll look at it in detail tomorrow.
