Honestly, it is hard not being able to share more or convey just the strict science of it, but I do what I do because I love it and watching a formula come to life is really why I do this. I can't fault folks for missing the jumps many of the tech people see, because yes, we'll never quite be at a PS1-PS2/PS2-PS3 situation again. But, there is still so much work to be done and the kind of worlds that are going to be rendered this time around won't simply be a visual jump and nothing more.
Just remember this word: D E N S I T Y
Biggest jump in gaming was 2D to 3D. Sure graphically games suffered in those early days, but it is something that had to happen. I still remember my jaw dropping when Microsoft showed off the Halo 2 gameplay demo at E3 2003(?). Of course, in the end the game didn't look or play nearly as well as in that demo as the OG Xbox couldn't run it.
