Would it still be worthwhile to buy a PS4?
Clear. Why not?
Just pick a nice bundle with a game you're into and look for an offer.
Yes, it would be, the PS5 is probably about 2021 ca so come out of the spin but even with the release of the PS5, the PS4 will stay long was back then with the PS4 and PS3 synonymous, especially for the PS5 eh at the beginning so good as no games come out become.
The PS4, or the PRO and the Xbox are still selling very well, I think Sony and Microsoft will not pop in there now and rausbringen the next generation. In addition, the consoles currently have enough power. 1.5-2.5 years, I think before, the new generation will not be on the market.
