Seems the 1/16 RC tank/AFV world is ever expanding. I've compiled a short list of stuff that should be available to us within the year or so:

Matorro Sturmtiger
Matorro King Tiger
Trumpeter/WSN Tiger I
Xion SdKfz 222/223

And of course the Tamiya Panther of which we're already aware.
I'm quite stoked about the Matorro Königstiger to be honest. Finally a 1/16 behemoth within my grasp or one I can easily justify purchasing. [8D]

Therein you will find pictures of the Matorro Königstiger prototype. And [link=http://www.rc-panzerketten-forum.com/wbb2/thread.php?threadid=7654]HERE[/link]. Nice.
