Bimmerfest posted a copy of the US 2014MY model itinerary that they got from BMW Santa Barbara:
F30: 328d, 328d xDrive
F10: 535d, 535d xDrive
All start production in July. The F15 X5 xDrive 35d is sticking around, but the 2014 doesn't begin production until December.
This is awesome news, as my wife was asking me just last week what we'll replace her 2007 RX350 (whose extended warranty ends in 11 months) with, and I was bemoaning the lack of powerful RWD/AWD diesels in the current market. Neither of us wants another SUV, so the X5 is out, and I thought that meant I was out of luck. Looks like my answer has come--535d it is!
