Is Uncharted 4 the generational leap we were hoping for? - Digital Foundry

Eurogamer:
"Gameplay reveals don't get much more exciting than this. This weekend's demonstration of Uncharted 4: A Thief's End gives us our first extended look at Naughty Dog's next-gen engine in playable conditions - and that's a big deal. After it was first teased at E3, the game was met with wild speculation and debate that would last for months over whether or not that level of visual fidelity could be achieved in real-time on current-gen console ahrdware. This brand new 15-minute gameplay demo helps to answer that question, while also giving us an idea of the kind of gameplay experience we might expect. Does the new footage stack up to the teaser trailer? Is this really a true next-generation Uncharted - or simply a prettier 1080p evolution of the existing formula?" (PS4, Uncharted 4: A Thief's End)
