If you still had any lingering doubts about whether or not Sony was set to unveil the PlayStation 4 at their special event this coming Wednesday, I think it’s safe to cast them aside.

Over the course of the weekend, Sony rolled out three separate videos. Each clip checks in at around two minutes and aims to gloss over what each console in the PlayStation line has given the world of digital interactive entertainment.

You’ll find the evolution of the original PlayStation at the head of this post, and you’ll see the evolution of the PlayStation 2 and PlayStation 3 below.

Now that we’re all caught up with what Sony’s given gaming, what do you think they’ll dish out on Wednesday?
