If you haven't seen what the The Walking Dead Season 4 Limited Edition will look like yet, here it is: ( http://www.mtv.com/news/articles/1722586/walking-dead-season-four-blu-ray-mcfarlane-toys.jhtml )
The limited edition will again be made by McFarlane Toys and will resemble the Tree Walker scene from episode 3 titled, "Isolation". Once you remove the Discs from the holder, the walker's arm and head reach towards you. It returns to it's position once you return the discs.
Looks pretty cool. I made the mistake of not buying the Season 2 Limited edition when it was selling at retail. I ended up paying MUCH more than that for just the Zombie Head alone with no discs. :/ won't make that mistake again.
I guess I will pre order from AMC. That is for right now. I will have to pay $10 something shipping. Amazon is the place I buy everything now a days. But, since it is limited, I will pre order for the time being. I made sure they did not charge me until they ship OR hold my money. They do not as long as I pre order with a credit or debit card. So, there it is.
