I definitely think the accessory pack-outs indicate that Medicom is treating these as "all in one" figures. Yeah, they've been known to do repaints or include extra parts for figures you were supposed to already buy, but releasing a figure with just a different colored t-shirt is a bit much ever for them.
My only gripe is there's no "light" battle damaged head with the main T-800 figure. I'm sure the fully damaged head will fit, but you know we're all "accuracy junkies" around here.
I imagine the problem with the T-1000 is the same that other companies faced: he has so many different looks, you pretty much need to make several completely different figures. I thought the very first McFarlane one all those years ago was cool with the exploded torso option. Something alone those lines would be good, but it would need to be able to look completely undamaged as well. The McFarlane one was permanently messed up, I think.
