Probably because they never actually showed the PS4. They went over the controller and hardware, but the console is never shown. lol
It is one of the more obscure webcomics I read, I usually let it go for a month or so then play catch up. Freakin weird, but in a good way.
I partake in a similar manner. What do you read on a regular basis? Me: Nerf Now: http://www.nerfnow.com/ Questionable Content: http://www.questionablecontent.net/ Penny Arcade: I doubt a link is required ._.
I also read Nerf Now and QC, as well as LICD, LFG, Girls with Slingshots, Chimney Speak, Menage a 3, Shades of Grey and a few others I cannot pull off the top of my head right now.
