What that means is this.
You order a car from Ford.
Ford sends it to Roush.
Roush builds it up a bit.
Roush sends it to your dealer.
So depending on your exact specs depends on wait time. If you want ANY Roush S1, it should not be long at all!
But if you have specific specs, Ford needs to build it, then send it to Roush. So it seems like at this point you are waiting for Ford to build your car and send it out. I am actually going out there tomorrow, pretty excited to see the place again. I love it there, it is like complete serenity.
