Sony’s VP of Publisher & Developer Relations Adam Boyes thinks that Remote Play is one of the best features of the PS4, but it's hard to communicate to the general public without putting a PS Vita right under their nose, as he told GiantBomb during an interview.

I think there's a lot to talk about, always. Remote play is hard to explain to somebody, without having that Vita in front of them.

With Assassin's even still, without the latency, they're like "yeah that's probably like..." And I'm like "No. I played that in the back, that was a real build. It was not fakery", So I think remote play is gonna be one of those things that when people get home if they have a Vita, they'll be "Boom", mind explodes.

He also mentioned that game sharing and streaming is pretty much in the same situation and it's easier to demonstrate in a live environment, because when you mock it up it looks "canned", with silly and fake sounding chat and similar issues that make the demonstration less effective.

Hard not to agree there: when I see that kind of social feature demonstrated on a stage, I can't help but paying more attention to the hilariously faked chat than to the feature itself. It's just too funny.
