The new design is fully modular(M-Space), in theory they should be able to swap diffrent core types/GPU cores round in almost any combination. Think the first few with BD cpu's will only have BD cores in and they will save the mixing and matching till after that's out the door. Looks like they have 4 modules slots to play with at 28nm. If the GPU modules turn out good, they could put 2 of those into those slots and have an amazing all in 1 chip for gamers. Extreme gamers will still be using the tri-xfire/sli setups tho
