That's why I was going to say! I've always been disappointed that we were not included in World Showcase. As for the 'Ireland' they have in IASW... well...
I have always wanted to see Poland added (b/c of the great food.) But now that Egypt was mentioned... I think that would be the best for architecture, a new ride, and a new/different type of food.
Egypt or Australia could have some fabulous theming. Brazil would make a nice addition and represent South America.....
Of course, if they'd have a stand, even a teensy little cart sticking out the side of a restaurant, selling authentic fresh-dairy Sticky Toffee Pudding from New Zealand, I'd be happy. Build any darn country you want, but give me the map to the NZ cart!
