A big multi-character trailer seems likely. It also seems likely that Shovel Knight is upcoming DLC, but I'm really trying not to get my hopes up in case I'm wrong. Wolf seems likely, since almost all the DLC characters are clones. Also, according to this http://supersmashbros.wikia.com/wiki/User_blog:David_eric/3_characters_slots_and_3_stages_slots!_(3DS_Version_datamined), there are only spots for three more characters and three more stages. Lastly, Snake would be awesome. I miss playing as him.
