they are supposed to be sorting out, forgot the name, but essentially unbalanced crossfire, touting that you can even use a onboard ati core to boost a pci-e card by 5-10%. not sure if that will ever happen.
frankly crossfire/sli isn't really a big deal at all, its not much of a problem as long as drivers aren't causing crashing. the biggest problem up till now has been, why buy two midrange that only just beat a high end card for similar/higher cost. its not worthwhile, and buying 2x £250-350 cards is just too expensive for most of us. but crossfire with 2x£120 cards with very very good performance is cheap and there isn't a £240 that can come close to what 2x 3850's can do.
