I imagine right now the HTC/Sprint team on EVO is up to their necks in fixing existing issues. You probably have a couple updates right there that all require development, testing, etc. Once they have settled some of the big issues going on with the EVO they'll move to testing the 2.2 version of android. I would just wait. Probably not until much later in the year. If you wanted cutting edge google then you should have bought the N1.
