It sounds like the file makers are making progress on the option files, don't give up on them yet.
Regarding the game itself, this article is pretty spot on. The CPU AI in PES is amazing, offering tactical and player variety that you don't really get in FIFA, at least not while playing against the CPU. The passing is great as always, and the controls are beautiful in their simplicity. What holds the game back for me, other than losing the licensing war again, are the sub par GKs and the sluggish dribble moves. There are far too many rebound goals, as mentioned, and even more goals that just shouldn't get by the keeper, period. I like the weight of the players and the pace of the game, but some of the skill moves are so slow (even latent feeling) that they are basically useless. I also feel like the deft touch dribble is far less effective this year. It is just far too slow, and trying to 'downshift' from a sprint to a 'jinking run' seems to cause an awkward slam on the brakes when applied.
At the end of the day though, it's a really, really fun game, and more than a viable alternative if you don't like, or are tired of, FIFA.
