Why is there no war machine action figures from the iron man 2 movie?

It seems since the movie came out that there's been a big explosion in movie action figures and mask with the hand blasters. I've been to Walmart and toys r us and many other toy shops and have found many iron man toys but for war machine I've seen not one. My 4 year old son has been wanting an action figure to play with besides the $50 one thats meant for display and not child use. Is it me or did marvel comic Inc decide that no one wants the black one?
