Metal gear solid 5 for PS4?

Could Konami's Metal gear solid 5 be coming for PS4? A recent Konami job listing suggests it is.
The listing states they are looking for someone to work on "the latest metal gear solid, targeted at high end consoles and PC."
It is also worth noting the image on the listing depicts Big Boss - so could we be in for another return to the pre MGS-1 era? Definitely one to watch!
