They could move things around inside. If the components got smaller, then consumption would decrease. With that decrease the cooling system could shrink a little as well. A form factor that was different from the Slim design would do wonders in improving sales for the PS3 brand.
They could bring a few things back to make the system a little bit like the original "futuristic" design. Like the membrane Power and Disc buttons on the front. Also bringing back the four USB ports would also be much appreciated.
