What i said was, even back when Shu signaled that emulation for PS1 and PS2 would be easier than using a PSNOW solution back in 2013, it was going to be about PS1 and PS2 Classics and not disk based emulation.
There has never been anything signalling possible support for PS1/2 disk based emulation on PS4, it has always been about PS1 and PS2 classics.
So, it only makes sense for them to focus on that and not disk support. And so i don't see where people expecting disk based support are coming from, cause it obviously isnt happening
