Although Sony has already announced its upcoming PS4 hardware specs, DICE studio executive producer, Patrick Bach, noted that nobody outside Microsoft and Sony knows the final specs of their next gen consoles.
"I don't know if anyone has the next-gen hardware to be honest – really," he said. "There are versions of it, but does anyone have the final hardware? Do we really know what the final hardware will be?"
Patrick explained that development studios (including DICE) working on next-gen titles are building them using alpha hardware with non-final specs.
"There are specs and alpha hardware, but nobody knows exactly what it will be," he said. "The only thing I can say about what we're building is that we've set the bar with what we can do and we can scale it down to 360 and PS3."
Earlier this week, DICE released the first Battlefield 4 gameplay video. "What you saw is pre-alpha - it's not the final game or anything," explained Patrick. "We are lacking a lot of optimization. Without going into detail about what it could look like on a lower spec machine or a higher spec machine, we will have the scalability to bring the most out of any piece of hardware."
