It looks like the Thundercats license will be a bit more expanded than previously thought.
The license comes through Icon Heroes, and beyond the SDCC box set, it looks like there will be at least two more box sets, each featuring 4 figures and one unarticulated figure. Also on display was a vehicle and a statue/playset.
Pictures can be found at Pixel-Dan. Thanks to Feroz Nazir (I should just let you post the news, cut out the middle man)

I am really excited about this. I can’t wait to have them on my shelf.
You’re welcome.
I’m just so excited and anxious to see all these wonderful new toys that I keep going back to those websites to have a look.
Like I didn’t expect to see Minimate Cheetara this soon!
Buying all of these. Now if we could just get Transformers and Teenage Mutant Ninja Turtles I’ll be the happiest kid on the block. And while I’m on future set ideas, I would kill for The Tick!
I like all three ideas.
I would also like to see Masters of the Universe Minimates.
A He-man and Skeletor 2 pack would be enough for me.
Just so I could pose them with the Grayskull cardholder by Icon Heroes.
Cool, but you forgot Gi Joe and Master of the Universe.
Hey I was wondering how can u get the othsr box sets with cheetara and wilykit. I jist ordered the boxset with liono. Im.trying to buy them all
The next box set is expected to be available at NYCC. It seems all the sets will be exclusive to conventions, and sold by AFX.
When is NYCC?
