Looked like a large building that can is separate from the smaller entrance building. Speaking of the large show building I really hope that the art they showed was just a teaser art and not finished. If all they do is paint the building grey and add a huge "A" logo I will be very disappointed. They really need to add a proper facade to match the entrance structure. It will also be interesting to see how they make the building fit with Carsland. A huge grey building looming over Luigis and dwarfing the eastern mountain range will not be very appealing.
