I want that stuff as much as you do... but the difference between that and Toy Story and Cars is that Toy Story and Cars have always made a fortune off of merchandising... I don't think Disney quite gets how huge Muppet stuff would be because in the past couple years when they had anything, it was all seasonal stuff they cleared out as soon as they got in.
I also don't like the fact that we have to wait for the movie's exact drop date for merchandise, and I especially don't like having to wait for the movie to do well to see more. There is no call on there being no Muppet merchandise to begin with in the stores anyway. What was the dumping of the Disney Dreams plush to bargain stores about anyway?
It's still a crapload more than we got from Up (a hit movie... there was NO excuse for the figure sets NOT going into mass production at all, they would have sold a lot more than their tepid Bob The Builder only he's hispanic preschool line) and considering we got like 4 bean bags and nothing else out of ENG (They can shove the bull about the movie being about "A king who loved his country" as much as they want... it would have been a lame Road to El Dorado clone if they didn't make it awesome). But then again, when they overmarketed their precious tween pop stars, they couldn't sell the merchandise at 90% off. They were flooded with a gluttony of useless and unsellable Hanna Montana and Johnas brothers stuff. So it shows they underestimate things.
Above all, no one's buying toys like they used to unless they're older collectors or 5 year olds. Everything has to be an iPhone app now. That's all anyone cares about. Though, there's no excuse why they never finished those other 2 Muppet Apps.
The fact that these plush, as soon as they hit the internet, sold out proves they're wrong about the slow and easy. Something tells me, even if the movie doesn't do well, the toys will still be a hit and we'll have to wait forever for more of them.
But the main point is... HEY! We're getting Pepe for the first time that you don't have to win out of a rigged crane game or bring your 5 year old cousin to a carnival and cry for. That's how you really win those things that take... what? 75 cents a piece to make?
