It looks like just the Incredible if it has to be currently supported, but if you think you can handle it, you can port it to pretty much any phone. But I'm sure that regardless of which phone you get, especially an HTC phone, someone will probably port it eventually.
Yeah, it does. It's gonna kill. HTC makes some of the best, most hackable phones out there. I'm on the Evo and anxiously awaiting what HTC might have planned for this summer. (though, if the rumors about Sprint's upgrade policy changing are true, I'll be waiting for the summer after that. *sigh*)
