It is not because they haven't released new games (not fully anyways) but because in the end all of their games are basically the same thing. With the economy the way it is I do not blame Facebook for doing the credit thing, but I think the real reason in price drop is that the hype is over with and no one wants to waste real cash on a simple get nowhere social game. They had mainly spent money because these games require people to have 100's of 'fake' friends on their profile, so many might of stopped playing or have made threads on the games wall with 'add me' topics so that they don't have to spend real money.
