I don't want to be that guy, but I should point out that summer technically ends in late September. We all think of summer as ending in August because school always conditioned us to view it that way, but "Summer 2019" could mean "September 22nd", technically speaking. Similarly with Banjo & Kazooie coming out in the Fall, which people think of as September/October/November, but could be as late as just a few days before Christmas. I'm not necessarily saying I expect that to happen, I'm just saying they've given themselves a lot of wiggle room here and there isn't actually much reason at the moment to assume he's releasing soon.
