We don't even know when/if the HTC EVO will be updated to Android 2.3 (Gingerbread), but if you want to see and hear everything that Google will be presenting at today's Android 3.0 (Honeycomb) event while it's happening, then be sure to tune into youtube.com/android at 10 a.m. PST to watch the live stream. It's the next best thing to being there in person and a lot better than following all the sites that will be live-blogging it.
There's bound to be a lot of surprises but I think most EVO owners will be quite happy with the release of the web-based Android Market, which features OTA app downloads/installlations, and Google Music, which is believed to be a music store and remote desktop streaming service rolled into one. Honeycomb details and demos are likely to dominate the event (cross your fingers for more info on that speculated smartphone support), but there should still be some goodies for EVO folk to enjoy too.
What are you hoping to see?
