Hall H went crazy last year when Zack Snyder announced Batman would team up with Superman, but imagine the enormous reaction from the crowd if they saw a clip of the two heroes suited up next to one another. Or even better a quick fight scene? Odds would be against a fight clip appearing, but even if the clip is Superman waiting outside of a bathroom while Batman takes a shit, it's worth seeing.
Clip from the reveal at San Diego '13.
