I think, there ll be some M3, which will be used on the track most of their lifetime (some people here do this, i live 60miles distanced to the Nürburgring). But most of the M3 engines ( like my prospective m3) will have to handle with a broad range of usements ( 30% city, 50% autobahn, 5% track, 5% abuse on the road  ). Therefor i think that my engine ll last for at least 400.000miles ( if the engine is warmed up every time befor any stress).

Your motor will be fine and even if it does blow, the BMW warranty will take care of it. I wanna say it was a rod bearing issue on the E46's that was plagueing them for a year or two before BMW ironed it out with updated rod bearings and different viscosity oil. I am not trying to scare you out of the car. As I stated, you can build a motor to handle the rpm, it will just cost more and require more precision, both of which BMW is perfectly capable of executing. My only point with the a high rpm motor was the fact that there is no free lunch.
