Keeping an eye on the X1 as well, either 20d or 23d. If VW brought a Tiguan TDI to N.A. there'd be some competition, perhaps stretching an A3 TDI...but my BMW diesel experience has been fantastic!
Latest I heard from my dealer was a X1 x23d for Canada (only xDrive, no sDrive) and the x28i some time in early summer 2011. Waiting would be hard for this...but doing ED over the summer would balance the wait.
