Konami Konami, why can’t you just put MGS4 on PS4 as you did with 1,2&3 in volume 1 ??

It’s a good thing this game is available in August for PS5 and Switch but people on PS4 will not be playing. This is weird as the volume 1 of the collection had 1-3 now they Volume 2 will skip PS4? Come on Konami , this isn’t MGS 3 Delta, you can do this.
