Exclusives (Sony) and shitty Canadian GPU prices would be my main reasons i'll be picking up a PS5. My tv I game on is 60hz for 1080p/4k but only supports 30hz for 1440p. So if I were to upgrade from my 2060/ryzen 2600x combo, it'd have to be something like a 2080 or higher for it to be worthwhile which would run me at least $900, not to mention a better cpu which is another $300-$400.
As I'm assuming the PS5 won't be more then $600-$700 total, it's the smarter decision for my current financial situation.
