The official Gears of War site now carries an Epic survey though I can't vouch for actual 'epicness' of the survey.
It craves the democratic blood of fan feedback, you'll need to remember your Windows Live ID though or the sweet victory of voting can't be yours.
"What’s the best part of the democratic process? Is it the campaigning, the debating, the red-white-and-blue tour buses? Nah, it’s the voting. Voting rocks. Now it’s time for Gearheads all across this great land of ours (you know, the Internet) to raise their Lancers high and let their voices be heard."
It's seeking to mine knowledge from gamers like which was the toughest battle, what multiplayer mode kicked the most gears and who is your favourite Delta Squadie?
