Yeah, I look forward to the new Bluetech diesels, even though this summer I drove an old-school diesel A4 in Europe and was really not impressed other than in connection with fuel economy.
If it is aimed at the 328 price wise but has the performance of the 323 (0-100 in 7.2), then I am not sure what success it will have other than with people who don't care about performance and will be impressed by the equipment package (which, mind you, is not that overwhelming in favor of MB).
