i think by now we have seen these websites mis intrepet things over and over.
and there is a difference between supporting 4k output via some upscaler or something ... which is fine.
but, the basic ps4 spec that ps4 games are coded to complie with - will not change.
can mark my works on that, e3 or whatever.
Sony are simply not dumb enough to break the golden rule of why console software allways beats out PC software ..and thats the closed box, that remains static throughout the course of the platforms full life cycle.
and sony have even less reason to figgle with that model being so far out in front than they ever have. it's always the trailing platforms that have had to resort to these add-ons etc to try and spin something to the masses to warrent a sales bump.
so no, we aren't ever going to see PS4.5 sw hitting the shelves, forget about it. no one is going to need to sell their ps4's in order to run their games in some increased poly count mode etc. is not going to happen.
forget about it.
and, thats a good thing.
i just hate seeing this constant urge for some PC like model console life cycle, the PC model is a total fail, why go that way?
but yeh ..just not happening, sorry.
