It is a hybrid this year.
It's tough to be a company, claiming your foam composite cores are the sickest, but then realize true wood cored dominate, and then all of a sudden in one year switch. It's just showing you were wrong, and most companies ego's are too large to admit that, so they slowly work into the wood core area. In a year or two I wouldn't be at all surprised to see them making all wood cores.
