Sprint recently posted on their Twitter page that the Sprint Hero and Moment smartphones will be getting updates to Google Android 2.0 operating system sometime before the middle of 2010.
"Happy to announce Android 2.0 is coming to Sprint’s Hero & Moment. Date TBD, but roughly 1H 2010."
6 - 7 months is a long time to wait for and update, but owners of the Hero and Moment should be still be excited. At least it isn't a full year like Microsoft fans will have to wait for Windows Mobile 7.
