By “Console testing still in progress”
Developer Toby Fox is currently working on an additional aspect of the highly-anticipated Deltarune Chapters 3 and 4, approaching an as-yet unspecified release date that is still slated for later this year.
For the moment, console testing remains underway. Our assumption here is that the Switch is part of these evaluations, but Fox hasn’t confirmed this in the BlueSky post. Instead, he simply mentions that testing has yet to commence on the PS5, with a previous announcement indicating that PlayStation trophies will need to be evaluated eventually due to their significant importance.
