The figures for the 1299 Superleggera (215hp) and 1299 Panigale R Final Edition (209hp) are unaltered.
I can't help feeling that this is convenient timing (to change the measurement method) as it provides a noticeably bigger gap in performance between the 1299/S/R and the FE, than previously, which might help fuel the perception that the cost difference is worth it. Particularly the R to the FE, where the gulf was previously not so wide (from 4bhp to 12bhp a 300% increase!)
