You cannot escape your destiny, you must own this figure from Enterbay.
I got mine from Toys2 - my box is great (sorry not trying to brag) - its a shame to hear about yours because the box is magnificent - a display piece in and of itself.
My figure has the different leg-length issue, I *cough* pulled his pants down to have a look and I'm not sure the problem is limited to the knee joint, it also looked like one thigh was higher than the other. And strangely the leg where the knee didn't look like it was 'in' all the way was the very leg that couldn't afford to be shorter. I decided to take no action, its not really noticeable on mine. I'm probably going to have him in walking/striding/mid step poses anyway.
I'm also anticipating a response from HT at some point. I wonder would they be allowed do 1/4scalers for Terminator or does EB have exclusive rights there. I know EB are doing a 1/4 scale Robocop and HT's announcement for Robocop didn't mention anything outside of 1/6
I have a feeling HT won't let Enterbay keep this to themselves and pay big $$$ to make one, so expect a 1/4 scale figure from them to compete. I am really looking forward to the 1/4 scale RAMBO.
