This is only my opinion, but I do hope Johnny, Sal, Pepe and Bobo are in the movie. I love the fact they're bringing so many old familiar faces back, and it's because of that, that I don't believe Pepe (or really any one Muppet) will cast a shadow over anyone else. This isn't me trying to complain, this is just me thinking about the fairness of each character, because I believe that, after 15 years, those four have earned their place with the others.
How about a hand for Bobby Benson, Link, Marvin Suggs, Thog, Beautiful Day, and all of these other awesome faces coming out of the woodwork? I hope some of those people have a line, even if none of them have really talked in the movies before. Link's only line was in MTM, when shouting, "They got married."
You can't judge much from a trailer, but I am hoping that Segel and Adams look at and treat the Muppet characters just as if they were other actors. While I'm not a huge fan of the Muppet films after Jim's passing, I can say I'm really impressed with Michael Caine, Tim Curry and Jeffrey Tambor for really shining through.
Oh... and honest to God story... this morning I was going for a walk, and I was listening to New Radical's song, "You Get What You Give" on my iPod, and I was thinking, that'd be a great song for the Muppets to do. Weird.
