the S5. RS4 is awesome but so is my RS6 so no need for me to go to a smaller 4 door, but the styling and features of the S5 I think i could get over the loss of 70 to 100hp for awhile. But don't listen to me really as I am keeping the RS till it dies and trading it or dumping it for an R8 I think i can afford (and in line for) in late 09.
