US orders for the new M5 (engine issues, of course, they tend to blow up apparently) are not expected to arrive until dec of this year. the M6 even later. the new 3 series is scheduled to arrive here in april, though. just in time to start duking it out with the B7...

first orders go to europe. no official word on US delivery but rumors are october/november of this year.

over on roadfly they're saying the new M3 will arrive in the US about 1 year from now. probably just after the M6.

If you compare the release of the new 5 and 6 to when the scheduled M5 M6 are suppose to come out, you have to figure that the E90 m3 will likely follow 2 years after the release of the sedan and 1 year after the release of the coupe. Roadfly may be right when they say next year, only with regards to the E90 coupe.
