Can MS & Sony just simply make next gen fully BC?

I dont know much about the PS3 emulator on PC, but I imagine it takes a CPU much capable than what PS4 has. Its the CPU where BC on X1 also struggles. Which is why Crysis nose dives in frame rate even on a X1X.

In the history of all Emulation efforts... You always need more CPU than the original hardware, goes for even the Xbox 360 Emulator.
The Playstation 3 Emulator tends to be superior than the Xbox 360 Emulator... Even in regards to hardware requirements, so much for the power of the Cell being a hindrance.

But Microsoft isn't doing 100% pure emulation anyway, so the issue is entirely moot.  - The Cell simply isn't a powerful CPU.

Crysis will get patched in time... Halo: Reach ran like a dogs breakfast for ages even on the Xbox One X before things were patched up... Takes them a few goes to get a hang of the idiosyncrasies of an engine.

I think the impression is specs will be similar enough to just run natively kinda like how PC does. Except PC isnt 100% compatibility with new specs and you can run into even bigger problems by running a new version of Windows. Either way, I imagine these are obsticles they're currently looking at.

Rarely happens.
And any modern PC can retain 100% backwards compatibility with all software made anyway.
