This is the way..
Also, SCAM!
Also also, some say CDPR blinked, and pushed it back so it won't clash with FFVII remake release date cos that's been pushed back too... or something along those lines? Anyways, it's a scam, even though we get a better game, it's still a scam.
Edit: April had Res Evil 3 remake, FF7 remake, and The Last of Us 2 release. I'm going with the idea that they do need more time, and it's way more profitable to not compete with these titlesy so it makes sense to push it back, make it better and have a much better first round of sales.
