SCE Worldwide Studios Shuhei Yoshida played a major role in the development of the PS4 and its games, and he played one in the North American launch of the console as well, where he appeared in a clip with VP of Publisher & Developer Relations Adam Boyes. He was especially pleased  by the launch event, and that was mostly due to the enthusiasm of the North American fans, as he told Diamond Online in an interview.

I have been present to the launch of many PlayStation platforms until now, but I think I may have been invited to the best one this time, thanks to the support and enthusiasm of the North American PlayStation fans.

Yoshida-san also explained the "victory pose" he performed during the broadcast, that was an imitation of Antonio Banderas in the 1995 film Assassins.

As for that image, when I won the game I did that victory pose involuntarily (laughs).

In fact, since using an animated GIF with Antonio Banderas was popular between western fans to express the goodness of the PS4 before the launch, when I did that imitation it was a big hit. I was proud like a man from Kansai.

Below you can see the new animated GIF featuring Yoshida-san himself (by NeoGaf user Canis lupus), that will probably replace the original with Banderas. Please Shu, never change.
