This guy again? Hell no.
He is getting paid to shit on Directs, something we are doing for free.
Nintendo would never be part of Summer Game Fest, we are doing this every year since 2020. People should stop acting like they would be there, they care about TGA to some degree (bringing Bayo Origins last year). But their support for TGA goes slowly down every single year, they realized they don't need to show there anything at all, they supported it early on because the Switch was not where it is the past few years. Even if Nintendo was not doing anything in June they would still not be part of SGF, why would you announce your games alongside other publishers when you can do stuff on your own (standalone announcement).
