^ that is a valid point too, although they've got a couple of the AMG '63' series motors out - the one that goes in the C63 is an NA V8 and sounds sick, hands down one of the best German motors on the road lately, but I was in a new SL63 the other night that was also great, but it was a S/C'ed 5.5L I believe. Anyway, AMG has the one size fits all thing, BMW M does bespoke treatments, true, different methodology, to get to what are seemingly more similar places than ever before. Obviously, making a bespoke engine isn't an overnight thing, but they do have to make the 7-series anyway, and BMW is no stranger to making bespoke power units. They even have the (albeit very small) side business of selling engines to cottage sports car houses, like Wiesmann. The same way AMG supplies Pagani, I think they could sell a 650-700hp V12 to a boutique supercar maker and maybe offset a bit of the cost, even. Counter-argument: If they can make a niche car like the 1M with plans to only make <3000 units a year, and knowing they've spent more than few years R+D'ing it, why shouldn't/wouldn't they make an M7, being that it could be only just as much work if they found something usable amongst the numerous V12's BMW currently makes (including the RR line) or a V12 variant on the V8TT they make now? It'd do well.
