Did you notice what he said? No? Here it is:
|Mike's an awesome guy, we're still working with him.|
The date for that video is February '10, i think its safe to say that they were already working for V.
Now i know this is a long shot but what i gather from that is Niko Bellic being in GTA V.
I'm just thinking, why not? Please don't bash me, i just thought it would be interesting to share.
