there is no reason to suggest that PS5 will struggle or fail. it's not a tick tock cycle where they do well one gen then struggle the next.
all this fanboy bullshit doesn't interest me anymore. i don't care who "wins" a generation. i'll be buying whichever console has the most exclusives i'm interested in playing and that would be Playstation right now. so let me just tell you....sony could release a PS5 that is significantly weaker/more expensive than the next Xbox and i'll still buy it. now before you think i'm a fan boy...i'd happily buy an Xbox if that had the games i couldn't play anywhere else. the reason i don't think i'll be getting an Xbox is because I have a PC. so technically i already own the next gen Xbox already
in fact my PC is probably more powerful than it will be.
at this point i think both consoles will perform almost identically. there will be small differences but nothing major. all it really comes down to is which platform has the most features/exclusive games and price.
true of any product. it's not gonna stop me buying day 1 considering i've bought every Playstation console at launch and they had no issues. if my PS5 has an issue i'll just get it replaced by Sony. no big deal.
