Is this real?

Hey guys! I was looking around on YouTube, and I found this video. I wanted to know what you think about it. It is supposedly a Half-Life 3 easter egg in Portal 2, that says "Fall 2013". What do you guys think? Also, it would be great if someone would take the time to try it out.

I think this is old and was already posted when it was uploaded in October.

Yes, that is absolutely positively without a doubt real.
