Pfft... everyone just hatin' because those guys look damn good in tights.
Seriously though, video is not mocking its competition in any way. People need try to watch these videos in another perspective. Does it make sense for Sony to mock Microsoft or Nintendo right now? If so, what reason do they have for it?
Now, what are the themes for these videos? Touchdown (football), Laser (sci-fi), Grenade (shooters), Heist (action), Dunk (basketball), and Goal (soccer). These have to do, like some people already mentioned, with the competition on online games but with a more... bizarre twist. But this twist has people talking already. Will it be successful? That's yet to be seen. Besides, at the end of the videos clearly states that it's a contest where people submit their own victory dance for a chance to win a PS4. There's no need to over-analyze this.
