I received a notification on Facebook, from HTC, that the update is still pending. The notification basically said "remember that the update was promised for the 1st quarter of 2010, which extends to 31 March." So while they may not be able to tell us exactly when, it does sound like it is still a definite plan.
If you are referring to the HTC Droid Eris FB page, it says that they are not affiliated with HTC, Android or VZW.
