Absolutely not, that's adobe premiere's workspace. Cs6 to be precise.
You can't do that kind of editing in AE, for example you can't have different pieces of footage on the same track, just to name one thing.
Trust me, I use both Premiere and AE ALL the time at work.
I guess I just think the simplest explanation is that the game will be called Metal Gear Solid V: The Phantom Pain and Ground Zeroes will serve as a prologue in the same way as the Virtuous Mission or the Tanker Chapter.
I don't know if he'll release the whole prologue as a demo though. Doesn't the MGS2 demo cut out after the Olga fight? Besides it's the next Metal Gear, it'll sell without a demo. Likewise isn't some kind of GT5 style early bite size digital release simply unnecessary? Surely Prologue only got released because Polyphony were haemorrhaging money and still nowhere close to release.
What we saw in the Phantom Pain trailer could be the beginning of the main mission, seems likelier than something toward the end of the game. I can imagine Kojima really wanting the player to feel the amputation and the limits it places on the character hence the fully limbed prologue. That could also be what he's talking about in terms of the risk he's taking and breaking taboos. I'd be disappointed if BB ends up with a flawless prosthetic arm soon after he leaves the hospital.
As far as Project Ogre, I don't really know. If those screens of the guy in the mountains next to the APC were Project Ogre, then based on that and the whole Mogren thing, yeah it's MGS5 and anything Kojima's said to the contrary is deliberate obfuscation.
So there you go; one game, might have a demo. My two bobs worth.
