Yep.— Phil Spencer (@XboxP3) March 20, 2018
I want it to happen so bad, but I don't think it will. Phil Spencer, the head of Xbox, has once again said that he's totally fine with Banjo and Kazooie appearing in Smash Bros.. While fans would love to see this, what would Nintendo gain from including the duo in Smash Bros. Switch's roster? They'd be promoting a pair of characters that won't otherwise appear on Nintendo platforms. It's not like a new Banjo-Kazooie game is going to come to Switch. The only reason they'd include the two in Smash would be to make fans happy. I know Nintendo aims to make people smile, but they're a business as well. I don't see this happening, but I really hope I'm wrong!
