I don't usually collect mechs, but this is one of the best things I've ever seen so I had to order one! REX is absolutely iconic, I love it's design.
They aren't delivered until late
August October late January 2013 so for now these pictures will have to suffice.
Edit: Rex has arrived.
Impressive size. The railgun is 59cm long.
Despite its huge size, it's not a statue. It's fully articulated and has features such as lights.
The railgun has an really cool looking launch sequence done with LED lights. You can see that in the following youtube vid: http://www.youtube.com/watch?v=mT70jjmUN-4&feature=youtu.be
And this is REX's original designer with the 3A version! This is in battle damaged mode with some of the armor plates and railgun removed.
