I don't see either of the two most popular characters in G.I. Joe being SDCC releases either. Both SE and SS and their many renditions will be full blown regular releases.
A Variant of the upcoming Crimson Guard perhaps?
Storm Shadow is big enough for a variant as a regular release. Would you accept Commando Snakes Eyes as a SDCC EX? I don't think so It would be a lame variant of a main character (ie CCC) or a trooper variant.
Black Sniper Viper Crimson Guard Elite Trooper Ninja.
There's always this hideous eyesore:What is a Crimson Guard if not Crimson?
The next Storm Shadow will be a 88 version...
Maybe a repaint of the Viper. He's been out for a bit now and they could have already gone into production for some kind of variant. Could also go with another Ninja since that would be easy and Ninja's are cool.
This is assuming we even have Zartan by SDCC.
