Looks like the 2009 e93 will not have any such modifications. From the BMW release:
"The 2009 models are: 328i Sedan and Sports Wagon; 328i xDrive Sedan and Sports
Wagon; 335i, 335i xDrive and 335d Sedans. The 3 Series also encompasses Coupes and
retractable-hardtop Convertibles; these continue with less extensive updates for 2009.
