Found this on the HTC Forum 15 minutes ago...
Here is something semi official from an Admin on the Sprint forum :
"Actually, the firmware update was done by HTC and released a while ago. It's not an OS update, just a small patch to fix some bugs. Google has written Android 2.1 - a far larger update than a firmware patch. Think Windows 95 to Windows XP. HTC is validating Android 2.1 on the Hero hardware and updating the drivers such. They're also updating the Sense UI. Sprint will get the completed package from HTC at some point and run our standard set of tests.
Assuming all that passes cleanly, it'll be available, possibly as an OTA, certainly as a desktop download and update to Android 2.1 When? No later than end of June (1H) this year. February? No idea. None at all. Sorry - I have no information at all on that. As I've mentioned, watercooler talk indicates that testing (somewhere) is going well.
Why not 1.6? Because it's the same amount of work to update to 1.6 as it is to update to 2.1. 2.1 is the latest and greatest version available from Google. By spending the time now to get ahead of the curve, our phones will be 'up to date' for at least 3 or 4 months before something newer and shiny-er comes out."
