Looks like someone's been reading Cracked...
Seriously, that is where I saw this, just yesterday. On that note, all this really is is an Easter Egg - it's like the Cavemen in Halo 3, there aren't actually cavemen on the Ark but it's just a little nod to the fans. Although to be fair, in that case the books kind of make it a possibility later on. Anyway, this newspaper is just a little nod to the Naughty Dog fans and a brief teaser of the next project the company worked on (i.e. TLOU). Can't really see it being a deliberate tie in like Portal/Half Life to tie the two games together...
