Sly 4 teaser discovered

Tatermoog, a user on youtube, had just unlocked all trophies in Sly Collection, and found a new option in the menu with lots of question marks. Turns out there was a teaser trailer for Sly 4 hiding in there.

Perhaps it's not a huge surprise given that Sony wanted to keep interest in the series alive with Sly Collection, but we're still happy to see confirmation of Sly's return.
