Unless someone wants to voluntarily get fired for not being able to complete "impossible amount of work" during regular shifts, then yeah it is. That's the culture they are harboring at Naughty Dog.
New (completely unverified and maybe out of someone's ass) leaks are putting this game's release as May 2020 along with a new Naughty Dog IP called "Stray's Cross".
“There is nothing about this game, nor the reveals, that hasn’t been one hundred per cent carefully crafted and methodically curated,” said Baker. “All I can tell you is that as much as you’re clamouring for it, you’re not ready.”
ND is being lazy in revealing the release date and new gameplay given the time since E3 2018 and in comparison with other big games releasing next year.
