Thank you !
I'm pretty confident with Geno's chance , the other square rep has several big issues if they want to get in Smash (Dragon quest lack international appeal , no request , no mainline DQ game on switch except DQ 10 in Japan, and is splited within Square , Armor project and a music compositer. Sora doesn't had a single KH game exclusively on a Nintendo console , no plan of porting KH3 to the switch , Disney , basically he'll sell but he'll promote a franchise wich is mainly on a competitor's console. And heck , I don't know a lot of KH fans with a PS4 , a switch , and Smash...) and he's the easiest character to get + several other stuff.
Anyway , I won't go too much off-topic. Banjo and Kazooie could be a good "break the internet" kind of announcement , unexcpected because of several legal issues , but beloved by so many that he'll basically get a revival if he's in Smash. Also , I still don't understand the people that think he can be a echo of DH... Like , would his down-b still be making him call a pixelated mexican to shoot at his opponent ? Would be hilarious , but I'm not buying it lol
