SCT is working on N/A tuning, someone posted a while back about them having a regular MK3 focus on a dyno.
I am not surprised Roush isn't making an S/C. Will someone else? Maybe. But Roush works very closely with Ford. They help put together engines for certain Ford models even. They can't build cars that are even or better than something Ford makes in house. Notice their RS3 Mustang isn't quite as quick as a GT500? (Until you bring it back and get the stage 2 kit for it.)
They flat out told us that 1.) The S/C car would cost more to buy than an ST, buy a considerable margin. 2.) They didn't think they'd sell as many, given that the ST is now out, and the fact that companies like FSWerks will be making turbo kits.
