What movie will they try to milk for another sequel next?

While at the movies the other day as the trailers ran Hollywood was trying to milk another sequel out of Terminator, and Fast and Furious. When the trailer for Jurassic park started, I knew it right away, talk of a trip, youngsters, the mother saying if anything chases you, run, then a ferry like boat headed somewhere. It is like the season of sequels on the horizon. What other movies do you believe they will try to milk another movie out of, or a few more movies from? If they are going to reach back into the archives to milk another Dumb and Dumber, to me there is hardly anything off limits unless the movie left no room for a sequel.
