Advice Needed i am stuck at ps4 or ps5

i am in the very poor country and want to buy a ps4 but should i keep my money and buys ps5 but it took 2 years of me or buy ps4 right now bucause ps5 on this country is 7.500tl in here but lowest payment is 2.800 tl and end of month i can keep very low amount of this money

Save for the PS5. Development will slowly shift towards next gen over the next few years and PS5 can play pretty much 99% of PS4 content. Plus it's a fantastic console

I would 100% save for the ps5. Like other people said the ps4 we soon be unsupported
