First, the fact that this has been discussed/debated since 2009 (based on when this thread was started) is wild to me. It's been a long time coming.
Second, I'd just recently heard that Pokemon was coming to Lost Continent and I think that's going to be a huge addition to Islands of Adventure. I have a 10 year old son who is going to lose his mind (I say as I just put down Pokemon Legends ZA five minutes ago). The Lost Continent area was one of my favorite areas of the park and I'm bummed at what it's turned into, but the theming has been a favorite of mine even now.
Hope this comes sooner than later, but I imagine we're still a ways off from seeing this come to life. Can't wait to see it.
