I only install roms, but really know nothing about the development and technical stuff, I have a question. Does the official source code need to be released to create a good sense rom with gingerbread? I've tried one that's out there and liked it a lot, but the battery life was horrible. It was ported from an HTC Desire HD if I remember correctly. Just curious, as I loved the rom itself and all the Sense 2.0 improvements, but I just couldn't deal with the battery life.
