I'm sure there are still some out there, but I haven't run into any. Most philosophers I know are compatibalists. Though to be fair predictable is not the same thing as determined, and we mostly think that determinism is false.

However, I think the true philosophical problem of free will is deciding what exactly a "will" is and what it means to be "free". You've got to answer that question before you can decide whether free will is compatible or incompatible with determinism.
