They're due out in 2013 and 2014

BMW is due to release a slew of new turbo diesel engines in the United States throughout 2013 and 2014. 

Among those in the diesel lineup is the F30 3 Series sedan diesel, due out in the first half of 2013; the F31 3 Series touring, due out in the second half of 2013; the F10 5 Series diesel, due out in the third quarter of 2013; the X5d diesel, due out at the end of 2013; the 7 Series diesel, due in the first half of 2014, and the X3d diesel, due in the first half of 2014. 

According to F30Post, a 180 HP 4-cylinder engine may be assigned to 20d or 25d models while a 255 HP 6-cylinder engine may be assigned to 28d, 30d or 35d models. However, no official announcements have been made in that regard. 

The U.S. had some other exciting diesel-related announcements this year as well, such as Porsche's first diesel model for the U.S. (the 2013 Cayenne Diesel), and Mazda said it was bringing a diesel engine to the U.S. by 2014

I don't think that matters that much. A gas engine should last well over 200K miles. And at that point, you have plenty of expensive systems in both gas and diesel cars that can fail, like the transmission, AC, etc, that can be a large percentage of the cars remaining value.

All the more reason to get a manual. They don't fail. Just the clutch does.

Tell that to the Synchros in my manual tranny.

It does matter, allot actually. Diesel engines have to be built to withstand far higher combustion pressures than gasoline engines do and they benefit from having lower a exhaust gas temperature.

Modern turbo diesel engines have between 16 and 18:1 compression ratios PLUS 20-25psi factory boost from the turbos. Gasoline on the other hand considers 12:1 high compression and 7-10psi on a turbo is the norm. You go much higher and you have a real hard time controlling pre-combustion on gasoline.

Ford designed and tested it's 6.7l Scorpion diesel to have a minimum of 250k service life under extreme conditions before internal rebuild. I would expect a real world average of 300-500k minimum.

It is not uncommon to see consumer level diesels with more than 500k on them.

Amusingly, at that point, the only thing left in any sort of decent state would be the engine.

Don't forget the exterior, interior, trim, and electronics. Just consider how many years it takes to get 250k+ miles on a car. Using the EPA's 15,000 / year figure, quarter million comes up in just under 17 years. Take a look around for rides from 1995 and see the shape they're in. Having recently bought a used car, mechanicals are often the last thing to go.
