I don't think that will matter much. My size was 19" for the old style frame and that is still my size for my Stumpjumper FSR. Most manufacturers still state the sizes in terms of a theoretical seat tube the length it would have been for a horizontal top tube, not the actual seat tube length.
My guess is that your size would be 21" or 22", or XL, possibly XXL.
