User blog comment:LEGOfan2010/Sonic Lost World Debut Trailer is out!/@comment-6576725-20130528220500

The Lost World could be Little Planet but I am not sure because Motobugs and Choppers weren't there. My Mobius theory could be right. And just because the trailer doesn't show any story won't mean there won't be. I bet the trailer is showing part of the intro like the intro to Sonic Colors.
