They have to fix dx9. It is not, what they really want but they have to run conform on package specs.
Concerning sli: sure the optimized profiles show, that this helps improving the sli matter, bit again: the technique is old and normally (to fully make their initial intention of sli work) the whole components have to be harmonizes up to high standard. The communication between the pc components have to get high end bus systems in every case. This harmonized complete pc will reach market as soon as the manufacturers of every part work closely together ->perhaps this will never happen!
Other possibilty: A manufacturer built his own solution all-in-one. First steps can be seen in the implemented gpu in intel cpus.
In current technical configuration, sli is for high end benchmark community or simply for those to burn money to heat up the room or to use more electricity for nothing.
Just my point of view.
