I have been using the leaked Eris Rom that has been ported to the hero for the past couple of days and it is excellent, but it is not full 2.1. There has been rumour in the past that the Hero, Eris etc will get an edited 2.1 but this is the strongest evidence.
The main missing features are no live wallpapers and no Google earth support. This very likely to be the same for the final hero release.
Todays Engadget article discusses that the fragmentation of Android (1.5, 1.6, 2.0, 2.1) could be the death of the platform without even touching on the very possible fragmentation of just 2.1 depending on your hardware.
