New free world
Well if the game is going to an end or not, i think we players should get a new free world. It should be inovative and different from anything we have in base game. That way i think it could finally feature apartments and swimmable areas. A beach city would be a cool and it could also bring lots of beach/sea related things that have been asked and missed in packs like Island Living such as: Mermaid Underwater lot (accessible from other worlds too), House boat, Kraken (that shows up on other worlds too), etc.
I'd like it to be inspired by Brazil, so we could have great sea background, the second latin rediential world and a chance to dive more into black and indigenous representation. I've really liked what they've been bringing from brazillian architecture to the game so i don't think it'd be much difficult.
But from difficulties they show to have bringing latin worlds as they do with african ones, i think it would be easier for EA if it was Australia. It could make sense and i'd like to see things from The Sims 2 (Console) tooike: Yatch/Cruise ship, Beach house, Surf station, Underwater Bio Dome.
I think it could also be a chance to finally get a Theater lot, so we could work as entertainer and actor. And don't forget about desert, strange animals and indigenous people.
