What is the real difference between Next Gen and Current Gen?

Hey guys if you are really wondering about the difference between next gen and current gen then brace yourself because this developer conservation may explain a bit about it to you.
So here is the post from one of my friend who has posted this on his page which seems to be quite interesting so it made my fingertips to put this on my blog What Next-Gen Really Means?
From The Mouth Of PS4 We have already seen next-gen but what does it really mean?
Hop in this article to know what next-gen means, straight from the PS4 developer.

So we just got this article from our source where Tina asked Dana Jan about what next-gen truly means.
There was a time when current-gen was called next-gen (PS3 and Xbox 360) and gamers had so many hopes from it like totally realistic gfx and more but those just turned to sand in the course of time.

 This interview was done when Dana was asked about the upcoming PS4 exclusive, The Order 1886. “For us, character work is something that I feel like people are just starting to scratch the surface on games that are really, really character driven,” he told me. “Certainly Naughty Dog has been doing an amazing job with things like The Last Of Us—that game is awesome.

 For us [a character-driven game] is really what we’re passionate about. We want to tell a great story. “Even when we worked on the PSP games, on the God of War games, we were more interested in what can we tell you about Kratos.

What can we show you about his character that you don’t know [rather] than what you already know about, like, can we make bigger monsters? We visited the family. We picked topics that, for us, were compelling just as storytellers and people.P

“Next-gen is kind of letting us go and do humans in a way we feel is like…I don’t look at them and just go, ‘Oh, that looks like an old Final Fantasy plastic mannequin face.’ It’s like, ‘Sure, he’s not perfect,’ but I listen to them talk and I see everything go on nuanced in the face and I go, ‘Oh, that’s a good performance.’

I’m even starting to see the actors that we cast come through in the faces and stuff because we actually get their personality. I think that’s going to be something that next-gen lets us really tap into.” Jan: “Next-gen is kind of letting us go and do humans in a way we feel is like…we actually get their personality.

I think that’s going to be something that next-gen lets us really tap into.”P Tina also asked them about how the PS4 has helped them in achieving what they had wanted. “Memory is a huge concern,” he said. “If you want to do high fidelity, like movie-quality, Avatar-esque faces in real time, the amount of data for one character with the facial joints we have, blend shapes and stuff going on to get fine wrinkles and things like that…For one character to talk for several minutes is a huge amount of data. “And then processing power-wise, the PS4 has a lot of graphical CPU power so we’re able to do a lot of complex stuff. If you look at the meshes of these faces, it’s millions and millions and millions and millions of triangles on screen all the time.

That’s something where you need that to get to the level of realism that we’re pushing for and it was never quite possible on PS3. Or if you were going to do it you would have to completely cater your experience around just that one character, high fidelity talking.P

 “We looked at the LA Noire guys—they had a real breakthrough with the projection stuff that they were doing on the faces—but you can only carry one or two people on screen at one time because it was being streamed off the disc. For this, the data would be exponentially larger, so I think the PS4 will let us see what else we can do with that.”
