Man,if the consoles were to launch in 2019 (which I still believe the are not) the RAM situation would be so bad..I mean,even for 2020 it looks like 32GB is not an option and 24GB is considered wishful thinking. If we are talking 2019,it's probably just 16GB.
Why does 16GB seem like such a low amount to you? I'd be more than happy with that!
