The wooden coaster has been nothing more than a rumor for years now. At this time there's nothing besides wishful thinking as rides go. The next IOA attraction should be announced in less than 2 years. Universal actually has quiet a bit of room to expand. There's nothing but wide open space to the right of USF. Not necessarily enough for another park, but it's something. There's also plenty of room in JP for a couple new rides. They haven't even begun to utilize that island. Before it was shot down, a Van Helsing ride was rumored to end up in the space between JP and the Lost continent. I've also heard about a small field behind Toon Lagoon. I don't believe there's any other open space besides that at IOA though. So those are the only 2 islands that can potentially expand. USF has some open space by MIB.
