WizKids has their final convention preview up with Superman and Superman (and no, that’s not a typo).
From the preview:
Greetings WizKids Fans and Supporters!
Sometimes at a convention, you need a friend to save you from yourself. Like telling you to take a break, or not to spend all your money on the first day, or teaming up with you in a game of HeroClix and saving you from defeat. Our sixth and final 2012 HeroClix convention preview is Superman and Superman, who stepped in to save the day when a Crisis threatened their worlds.
