Take this with a mountain of salt, but... apparently Liam Robertson said on a Patreon exclusive podcast that SCVI will be one of the games shown at Namco's event on the 15th. (

I kinda have a hard time believing this, since the info doesn't seem to be from a reputable site and there's no way to verify the claims right now. BUT if this is what Robertson actually said, then I definitely believe him. (For those who don't know, this is the same guy who leaked the existence of that Mario and Rabbids game before it was announced, as well as the return of Metroid.)
