Also, game companies aren't going to announce price drops until they happen. Announcing it would just delay people buying them until it actually dropped. Sony has a history of saying "We are not going to drop prices" right up until the day before they drop them.
But, I'd have to agree with most people here...prices probably aren't going to drop until after Christmas. Bundles and rebates are good values this year if you need what is included. That certainly sweetens the deal over what prices have been the past year. I'd speculate around March or April you might see another price drop after inventory is back to regular levels and sales are starting to sag.
