Actually, there are plenty of items out there for customizing your own Joes and Co's (Cobras)! I've been doing it for a while, ever since SS dropped out of the license. I shifted more towards the superhero realm in the last few years but I have been gathering the items for my G.I. Joe characters and mostly have what I need for every figure that I'm looking to craft:Your probably right on release timeframe. I bet most likely upper echelon characters for release but wish we could get some others too. alot of unique character's with no parts for customization yet.
Torpedo, Dial-Tone, Grunt, Mainframe, Airborne (bet many of you would like to see this one!), Zap, Clutch, Wild Bill, Ripcord, Low-Light, Scarlett, Lady Jaye, Cover Girl (I have what I need but looking to see if ThreeZero produces the first 2 ladies first), Eel, Copperhead, Snow Serpent to name the ones I can think of top of my dome.
Already completed: Footloose, Tunnel Rat (mostly and sans the face paint which I'll get to eventually), Hit & Run, Alpine, Snow Job (I'll probably upgrade the head), Recondo.
