@Lurch, I agree. I'm pretty sure sales would suffer if a new / improved console were to come out every 2 years. I think there is a lot of hype surrounding Scorpio and hype leads to disappointment, even if it lives up to at least the majority of what MS claim it will be. I can't remember the last time something lived up to its hype and I've heard that PS is dominating the market, so why flinch when a competitor tries to make ground?
Tech may be moving quickly but I think the PS4 and Pro still have a lot of potential left before having to be replaced by a superior machine.
If the half-baked Pro wasn't released just a little while ago, I think people in general would be more accepting of this rumor. That, or if PS5 promises (and delivers) on key customer requests (full BC compatibility, etc. etc.).
That's my 2 Zim cents.
