Awesome characters, I hate Petey Piranha but I like the plant. Neat inclusion that I didn't see coming.
Anyway I'm hoping the DLC includes:
1. Banjo
2. Chun-Li
3. Tifa (Little Mac echo?)
4. Lara Croft
5. Iwata (with Sakurai echo)
1. Banjo (Phil Spencer is ok with it, so it really is up to Nintendo)
2. Rayman or a Rabbid. I think Ubisoft and Nintendo's recent partnership could make this happen.
3. Dante from Devil May Cry
4. Another Sonic character ( Shadow, Knuckles, or Tales)
5. Raiden from Metal Gear Solid (I think it would probably be more likely that a Xenoblade 2 character though)
Thats off the top of my head. Im sure some others can think of characters that would make me rethink this.
I never thought about this until yesterday, but Bayonetta, Cloud, and Ryuu was all DLC characters. Maybe that allows both parties to make a little money off DLC with some kind of deal, because then you know how much a specific character sold.
