Dude, not to sound like an ass here, but this isn't rocket science. I like Persona Central, and I admire the effort you put into your work. That said, this was dumb.
There was absolutely zero reason for you to put yourself out there and tell people that P5R is a Switch game, and then go on to mention it might even be a Switch exclusive. I mean if you really can't see how you brought this upon yourself, with the dozens of examples where this has happened to leakers before you, I'm not sure what to say.
The point now isn't even whether or not a Switch version is announced in March. It's that you brought this upon yourself. Nobody asked you to "leak" the existence of a Switch version. Nobody asked you to claim it may even be exclusive to the Switch. Nobody asked you to come on here on ResetEra and then fan those flames even more, mere hours before the announcement was meant to happen.
People are upset because you got their hopes up, and now they're disappointed. And there was no reason for you to have done so. It's that simple.
