Lest anyone forget: SMT was only announced and entered development in 2017.
Persona 5 was in development since effing
2008. It was only officially announced in 2013. And it got delayed and delayed until 2016.
Project Re Fantasy was announced in 2016, and we haven't heard shit about it since.
Not to say that the wait for any of these games isn't annoying, but Atlus kind of has a track record over the last decade of taking forever to show and complete their big projects. The smaller stuff like remakes and spinoffs get pumped out, but not the core titles.
