Would it be safe to assume the 8-speed transmission is only available on the 8 cylinder engine like on the 2011 5 series? If it was on all engines then the 35d may get some fuel economy savings which would be worth waiting for a 2011 model. It would also put the N55 engine in play for making similar, if not 'better' numbers than the diesel. I'm on the fence myself about a 2010 35d or wait until 2011.

With the Canadian 5 series press release stating they are coming in June 2010, could they have a later X5 release that says they are coming in April? I hope some official news is posted soon.
