I've played "Hollywood Stock Exchange" almost since the website opened. It's a free game where you invest fake money in real movies. Depending on how the movie does, and of course, how many people buy and sell the stock, you make more fake money.
I started with 3 million dollars (everybody gets that to start). Now I'm at 22.4 million, and am rated in the 95th percentile (only 5% of the players in the game are richer than me).
Getting back to your question, about what movies are coming out... This is one of the fun things about playing the game, you get really into what movies really are coming out from the planning phase, to shooting, to wrap, to release. The whole time you are tracking actual films.
Here'a link showing movies that they track that will release between now and December 2009:

Of course, if you want to play the game, you just register on the website. It's free and fun:
