I found some interesting things looking through LinkedIn.
This
guy had been with Sony almost forever but it seems he helped in the concept of a new Life Simulation space for PS4. So, Home 2.0 on PS4?
It was also interesting because he was art director on an unannounced PS Move title, but in the summary, he states that he was art director for The Universal (unreleased). So, maybe this title was cancelled.
According to this guy's
profile, he was working for Studio Liverpool and you can see Wipeout for PS4 and Project X a 1st/3rd Person Shooter for Vita/PS3. My guess is that Project X was the Splinter Cell style game for PS4 that Eurogamer mentioned in this
article. It probably moved development onto a Vita/PS4 game instead.
