Price and launch date are not precised yet, which is frustrating, but it's pretty much expected to be 499 and in early november. If either of those predictions end up wrong, they'll be in trouble because they'll have failed expectations which is a very bad marketing position.
On the positives, the Sony showcase was the best console launch showcase I can remember, as long as if we consider it was 100% straight out of the PS5. Traditionally we get lots of bullshot CGI, a couple games that will be delayed 2 or 3 years, and a couple games that will be outright canceled, some games from unproven teams or studios with no gameplay, and long pointless segments about sports franchises that come out every year anyway from 3rd parties.... It's crazy the number of critically acclaimed new franchises Sony managed to come out with during the PS4 generation, which will have a continuation on PS5. Those are day one purchases for me without even looking at reviews. They don't need to hype because they delivered last gen, so we expect those same teams to continue to deliver next gen.
I'm worried about not being able to secure a preorder, but I also feel that's such a stupid first world problem.
I also want a teardown but it's just the curiosity from my electrical engineering background. Nobody "needs" a teardown.
