It is probably mostly the same crew, but the point is that they did the rebranding because they wanted to distance themselves from the Penny Arcade site and comic:
“[…] You’ll notice that it is no longer the Penny Arcade Expo. It’s outgrown us and it belongs to the gaming community at large now not just PA fans. Someday I expect to attend a PAX and not even be recognized. […]”¹
Therefore, I believe it is incorrect to say that Intel revealed this product at “Penny Arcade Expo”.
> I think the main point of the original poster was more that this is at a gaming convention, though.
And my point was to simply correct the name used; PAX used to stand for Penny Arcade Expo; now it doesn’t, so we shouldn’t call it that. I’m still not sure what all the downvoters think I meant.
I think it's fine to still call it that descriptively; I don't agree that an official rename means we "should" do whatever the corporate branders desire. It still is the Penny Arcade Expo in the sense that it is an Expo, and it is owned/operated by Penny Arcade. It's true that the Penny Arcade corporate marketing team has officially redefined the initials as not standing for anything, but that's only really binding on their own marketing materials, not on everyone else.
