this is a really good sign because it shows how much people loved this movie. and very good point about this being the way we start reeling in the kids
i think that will happen for sure, and i think the next movie will be much bigger because of it. the people who loved this movie are going to show it to everyone who didn't get a chance to see it, and especially to little kids so they can get into the muppets. and that'll be the key to the next one's success
this always happens with sleeper movies, ones that maybe weren't gigantic hits in theaters but had really passionate fans (like anchorman, fight club, or the first austin powers). the fans jump all over them when they come out and show it to everyone, and the movie becomes bigger on dvd. not that the muppets wasn't a hit (it was) but i think the reason it didn't get to 100 million was precisely because little kids didn't respond to it because they didn't already know the muppets themselves
but now they're going to get it force-fed to them on dvd and then probably the old movies and stuff, so that they're all ready for it when the sequel comes out
