That's the thing with Nanco... Some of their plush looks REALLY good (basing it on a variety of licenses, that is) some of them don't. The Simpsons ones tend to look as good as Simpson plush and 3-D merchandise could possibly look.
I'm guessing the Pepes on e-bay are all used and stuff too... I dunno what to say about used plush... all dusty and stuff.
It seems that, quite obviously, any and all Muppet merchandise WILL coincide with the next movie. We just don't know if Pepe is one of those characters. I'm very disappointed that the Pook-a-looz line isn't being continued (at least to my knowledge... some say the rare Miss Piggy was produced ONLY for the surviving FAO Schwarts stores... but that's about it. Man, I really was hoping to see Pepe, Chef, and Beaker (which would have been perfect, as his head ALWAYS sinks down into his shirt), but that's not very likely.
This IS word that there are prototypes of Disney store specific Muppet Plush shown at Toy Fair this year... but no pictures could be taken of them... and I'm guessing they only had the main Kermit, Animal, Fozzie, Piggy and Gonzo stuff... it really is a shame Sababa didn't give us Pepe... I mean, they gave us the FIRST plush representations of the Electric Mayhem... 3 versions of Janice (2 smaller ones in sets, one actual full sized ones) but no Pepe.
