Mattel shouldn't have announced it, I was thinking about buying the Nightwing rerelease that's packed with Clayface and Catwoman (assuming I had ever found the wave).
Definitely hoping they're both new sculpts, although they would even be fine with modification - though the Nightwing headsculpt that was on the blue/yellow version was better. Wonder what the variants will be, maybe Stewart as Green Lantern and Grayson as Robin?
Here's hoping it goes: wave 4 - Wonder Woman, wave 5 - Martian Manhunter, wave 6 - the Flash. Though, that would mean Flash wouldn't be out until 2009. >_<
