Yes, I didn't think this would happen either. I was unimpressed with the Jumbo concept when it was announced, saw some in person and "got it," and I'm now waiting for a few key figures to pick up once they are made. Now I feel like a Jumbo Rebo Band is actually gonna happen, too. That is really cool, and something I would be willing to buy.
Forget the Jumbo Rancor, the next "impossible" benchmark that I would love to see them tackle--Jumbo Death Star Playset!
