Now that promotional Splatfests are a thing in the West, what else would you like to see? I think there's a lot of potential for some really fun promotions.

I for one would like to see a Doctor Who themed Splatfest - perhaps Daleks v Cybermen? The Inklings could wear a makeshift Dalek eyestalk or the Cyberman helmet depending on who they chose. Star Wars could also be really cool - Jedi v Sith?

I could also see Nintendo doing some promotion for their other franchises. With the 30th anniversary of Super Mario Bros coming - on a Sunday no less - I can see there being a Mario v Luigi Splatfest to celebrate, complete with Mario/Luigi hats for the Inklings to wear.
