A teaser trailer has been discovered in Sly Collection, which hit streets Nov. 10, and it seems rather definite that a Sly 4 sequel is coming. When? Well that's probably what the question mark's all about.
Reader tatermoog filmed the trailer and stuck it on YouTube. It seems to be an unlockable but he's not sure what triggered it. He writes:
Just finished collecting every single trophy in the Sly Collection (including the minigames), and noticed there was a new option under the "Credits" slot in the main menu. Tried it out, and much to my delight, it was a teaser trailer for Sly 4. Not sure how it unlocked (if the GoW Collection was any indicator, it was probably platinuming all three games).
He adds, "I hope Mike Fahey is as excited as I am." We're sure he is, tatermoog. We're sure he is.
