Yeah, I don't expect a Zelda blowout for June - as others said, in 2016 the spotlight was so intense because that's all Nintendo had ready to talk about, given they weren't ready to reveal Switch itself.
They've got releases to talk about immediately after any early to mid June event (not that they'll need to go big on FEW, Strikers, Xenoblade 3, or Splatoon 3, but I'd assume footage and reminders happen), plus Bayonetta 3 waiting for a release date, and probably some other things to announce for later this year and perhaps something to show for 2023. Plus, actual third party support.
