It's still far too early to go guessing.
I can remember less than ten years ago when the "experts" claimed that gas giants couldn't exist close to their parent star. This kind of talk pretty much ended in 1995. Instead of blowing more hot gas into the interstellar void, they should put their energy into designing new space telescopes to give us real answers. A new Hubble with a 5 meter mirror and the latest in electronics would be a great start.
