hmmm.. Jim hinting that the biggest changes still haven't been announced?
OK I'll bite...
16tf GPU confirmed ;)
however I suspect that it isn't going to be that, I think it will have a smaller TF count than the xbox series x, but will offer way more unique stuff just like the dedicated share button or touch interface that the DS4 had..
If I was to speculate, integrated additional hardware to allow twitch streaming (so there's no sharing of cpu / gpu resources)
if i was to just throw all rationality to the wind and just wildly speculate, then
hardware to allow the streaming of VR to the PSVR2 headset (it will be a wireless solution)
dual GPU's with the second one solely dedicated to RT (although the graphics pipeline would be a bit convoluted)
a second 'daughter board' with a seperate cpu / gpu to deal with streaming (see above).
or
it's a hybrid, that is in effect a ps4 portable in handheld mode, but a full blown 'bells & whistles' PS5 when docked.. (this is one i don't want, a jack of all trades, which the switch already does successfully and something Sony doesn't need to do).
What I am expecting is exactly what I want, more of the same, just more powerful. Sony don't need to mess with the basics. it works (and 100m + sales prove their strategy was the correct one). They don't need to re-invent the wheel. Let Nintendo do their stuff, let MS do their stuff, no need to compete with these if you don't want to.
