Well I talked to another Tech Support guy from Verizon today. The story I got from him was 2.1 will be out for the Eris within the next 30 days(Anytime in between) unless they find more bugs with it. From what he said they have been testing 2.1 for a while now and when they find problems they have to report it back to HTC and HTC has to address the problem before it can be released. So looks like to me its a testing game then a back and forth between Verizon & HTC until everything runs smoothly. Hopefully this will be the finished product and we will get it within this time frame I was told but who knows. I contemplated Rooting to 2.1 but I'd rather wait till an official OTA that way everything works as it should.
At least this is the 3rd Tech support person from Verizon that has told me that the Eris will definitely be getting 2.1 and all have had about the same ballpark time frame. Hopefully this will be the last delay for a long awaited update for all of us Eris owners. I know I'm keeping my fingers crossed.
