All we really know about the game itself as of now (correct me if I'm wrong) is that it's going to be for the Wii U and 3DS, right? As I understand it, the mods are touchy about SSB threads; don't start flame wars, guys. Even big threads, such as the "Disturbing things in Pokemon" thread, can be closed. I'm personally hoping for Cthulu and Magus/Janus from Chrono Trigger to star in the next SSB, but I'm not going to start an argument about it.
More on topic, Spear Pillar, a specific place from the Pokemon games, was made into a stage for SSBB. What places in Unova could be made into stages?
