I have been doing some research and this could be the first year without a video/trailer for anything Xenoblade/Monolith Soft related since the announcement of Xenoblade at the E3 in 2009. Every other year since 2009 there has been a Xenoblade video or trailer. The last video there has been of Xenoblade was on April 19, 2023 (Future Redeemed trailer) or in the Nintendo Direct on September 14, 2023 where they announced the Noah and Mio amiibo.
If there is nothing from Monolith Soft in the Nintendo Direct of June, then they will definitely announce their new game at the Switch 2 presentation and I think it will be the action game. It will probably be the biggest and most ambitious game they have made to date due to the time they have been working on it, the amount of employees they currently have and the hardware of the Switch 2.
I'm very excited.
