Is it worth getting ps5 if they're still making new games for ps4? They don't make new games for ps2

It is definitely worth getting the PS5. I got the digital console edition and I brought the Seagate 4 TB internal M.2 SSD Storage As Well As A Christmas Present To My Self. You also can get a external storage device for your PS4 and transfer all your PS4 games over to your PS5 and you can play your PS4 games on your PS5 as well that's what I did in my PS4 is in my closet right now.

Yes

Someone I know described the PS 5 as a PS 4 pro in a fancy wrapper. the game catalog isn't where the PS 4 is at as of now. Personally, I'd wait and see where the PS5 will go in the future. Of course that the opinion of a die hard PC gamer, not mine, I'll play on any system.

I'm getting custom covers made for my PS5 so it's not going to have the white shell on it anymore it's going to be all blacked out with my logo on each side of it.

I don't know. The PS5 has been out for 2 years now, and it hasn't gone down in price, and they're still playing games, dicking us around where availability is concerned.
