If you look at the G1000 on a DA40 TDI, you'll find many software features that have been released in the past 6 years, such as flight logging, wind vector options, vertical navigation, IAP minimums and synthetic vision are not available. Diamond have stated that the only way to get them is to upgrade the aircraft to an NG. That's a pretty shoddy way to treat their customers, in my opinion.

I guess the fact that most of the weight increase is in the nose can't help. They also changed the winglets to reduce drag and that may have reduced lift at lower speeds.
