I don’t know how I missed posting about this tech demo that I first heard about shortly after the PS4 grand announcement earlier, but it’s important to note that this is working on PS3. That’s right, PS-Trizzle as Chad Warden would’ve called it back in the day. 😛
Makes me wonder what PS4 will be able to do if something this good is currently available for current systems. 🙂

Actually, this video is older than you think, it came out in March 2012. The demo that Quantic Dream showed off for the PS4 is the old man head.
All the more awesome then if this type of stuff was available last year. 🙂 I updated the post to reflect that I first heard about this trailer alongside the old man demo rather than it making its debut since I got the demos mixed up. 🙂
