I would like to see some new countries in the World Showcase, but if space is an issue, I think I may prefer to add a ride or two to the existing countries rather than add new countries. However, I don't know how much extra room they have behind each pavillion, so they may have room to expand the countries to the rear by adding rides, as well as room to add some new countries.
I wouldn't mind an Australia pavillion...especially if it was complimented by an Australia at Animal Kingdom. Perhaps Russia and, as someone else has said, Greece.
Journey to Center of the Earth (AK)-sounds good
Dark ride based on Disney Villains (MK/DS)-sounds good
Australia (AK)-Most Definitely
Dark ride Village based on B&B, Pinocchio and an unmentioned (MK)-I wouldn't mind
Indiana Jones Show Replacement with ride (DS)-I'd rather leave the show and add the ride
Alice's Labrynth leading to a Meet & Greet (MK)-sounds okay
Incredible's attraction (EC)-how 'bout let's not and say we did
Brother Bear (EC)-possibly...depending how it's done. Making it a ride in Canada sounds okay
