depends if you want to save money, then go for a ps4 on some kind of sale. If you want your console to have a longer life, wait for ps5. Depends on what your "needs" are really
I would look up games that you like first on youtube or twitch find games you may want to play but i dont think it will be worth buying ps5 with maybe 10 games to play at start and i hear this generation of gaming systems may be pushed back because that virus in China
Better to buy a ps4, besides having countless games, the price is lower, many promotions to enjoy and a lot, the ps5 is in its initial phase, as the ps4 in its launch there were many errors, many consoles burned already others had problems in your reading, it is better to wait
