While this isn't that big of a deal in having to wait a few more months to play LoU2 during an already busy first half of 2020, the manner in which the release date was announced and then delayed a month later is concerning.
It makes me trust Sony less and worry about the state of the game. If it's development timeline is this unstable this close to release, what else is unstable? Not a good look. I'm not "angry" in an entitled, angry gamer sort of way, but I do think this sort of delay is a big deal and unprofessional for what it says about Sony, Naughty Dog and the development of Last of Us Part 2.
