It looked like we were still getting the same biomes, but there seems to be some offshore industries, helicopters, and looks like more of a focus on roads and cars this time.
I am also intrigued by the "are you ready to connect the world" maybe logistics across save games, or an optional multiplayer mode?
I really hope that there's a "fit to terrain" or something like that for track/road placement because currently I always spend ages building in little segments and perfecting the N and M keys until it's the cheapest possible (least terrain modifications)
