Yes that's the one with the weird ending with Nintendoland. Urgh, what a misreable E3 it was.
But didn't they decide not to reveal Starfox Granprix last E3 ? Wasn't there some chatter about that.
No one said anything about them revealing Star Fox GP at E3 as far as I remember. The insiders only said it's real and looked like it was a 2019 title.
