I think I get the idea of the SSD Claim, as my friend pointed out. Probably just clever marketing.
The SSD is better than anything on the market right now, until one is released next month, which then beats this claim.... And once released in 18months, SSDs will be even better.
As for the ray tracing they have mentioned. I watched a digital foundry video yesterday where now, RTX can be done through software, so no real need for the new graphics cards.
So my 1080ti will be able to use ray tracing, but the performance of doing it this way is absolutely pants right now, so try cramming that into a console and it'll definitely be stuck at 30fps yet again.
I made the switch to pc just over a year ago, and honestly, my only regret is that I didn't do it sooner.
