As BMW keeps stressing, the E92 and E93 M3 models are meant to be with us for at least 1 or 2 more years, and there won't be any new M3 until these are out of production.
They're probably talking about "model year" years, right? i.e. 2012 and maybe 2013 model years.
Present: 2013 M3 coupe (Azurite Black, Black, Piano Black)
Past: 2010 335i coupe (Monaco Blue, Cream Beige, Grey Poplar)
