There are a lot of solid boxes that Sony's ticking: backwards compatibility with the previous generation, sticking with physical game copies instead of moving towards a "games-as-a-service" cloud model, updates to hardware that justify the new console's number increment, releasing devkits early to get game devs on board with said hardware, etc.
That being said, as others have mentioned, the support for 8K stupifies me. As far as I understand it, 8K displays are only just now becoming commercial, and only for the highest buyers. I'd much rather have higher, consistent framerates.
Ray-tracing, I'm indifferent to. If they can make it work, great, more reflective windows and puddles for all. If not, then perhaps game devs can choose not to implement it.
Shame there will be no additional information on this at E3. Makes me wonder if they're saving their winning hand for a future round of poker, so to speak.
