These companies purposefully don't address rumors, because once they start, when they don't, it's as if they are confirming them.
It's also not the first time a game was announced with its own PlayStation Blog post that ended up being nothing.
I’m Michael Armbrust, the creator of VizionEck: a first-person shooter unlike any other. I’ve hinted aspects of the game, but now it’s time to wipe away the mystery. I’m here today to reveal all and premiere the gameplay video.

I would be surprised if anyone on this forum knew about this game. Announced way back in 2014. The creator of this game was a forum goer on VGChartz who was part of the PlayStation community over there. Some of us left that forum and he created his own on his website to invite us to continue discussing things there. Away from the ridiculous moderators of that place. He informed us then that he had been working on a PS4 game. Which was this very simplistic game that he was hardly ever any closer to releasing after years of development.
Well, we very soon realized the kind of person he was. Quite the braggart and possibly an alcoholic. He started becoming woke and worried that someone like Anita Sarkeesian would see his forum and put him on blast for everything we would say on it. Which, honestly, was even less than what gets said around here. So he started deleting posts and threatened to punish people for saying anything that might get him in trouble with the woke crowd. I was one of several people who left. Now he mostly talks to himself on his own forum though there are still a handful of people there from the original group.
He is still working on that game supposedly but it has been reimagined as a type of battle royale. Keeping in mind that development on it started more than 8 years ago. He is also supposedly working on several other titles. Only one of them actually released and it was on Steam for $10. One of those trash games that just clutters the store. So, people might be surprised that Sony gave this guy any time in the light. Don't be. It's not the first time Sony used their blog to put attention on a game from an unknown and unproven developer that ultimately didn't amount to anything.
