I can't believe anything until I see a BMW publications stating these items. Seems like a drastic change and it would have to be one revamped N54 to be able to handle all that power. HPFP would need to be upgraded, advanced cooling incorporated, etc. Under that kind of stress I would wonder a bit about longevity but I just like everything else, BMW will pull it off and make it worthy of the roundel.
