New world in the Dream Home Decorator game pack?

The original tweet was actually about what world would you play in and what lot would you start on. There's a possibility for a new lot type coming with this GP. I do think it's strange if there's a new world or lot type and they haven't already shown it off though - but they did say 'there is still much to reveal' when they tweeted the trailer. It's possible they're drip-feeding us information, to keep everyone glued to the twitter account and livestreams. Followers=money, after all.
