The FFVII real time tech demo was a PS3 demo with as much detail as you can put into a single scene on the PS3 without to many set pieces. Not what you would realistically be able to do if you wanted a large number of set pieces.
This however is a completely different story, the real time here has thousands of active characters at any given time and looks like a CGI from this generation. If this is indeed the true power of what the PS4/720/Next-Gen PC's can handle...than WOW huge, huge, huge, HUGE processing boost from this gen to the next.
Were talking around 16 Gigs of Ram for this to be even remotely possible, let alone the GPU/CPU.
...uhh...ill just put my favorite quote of all time here.
"Welcome to Pain, the second of three...You have dealt the first...now deal with me!!"
