I would say some things look better and some things don't.TLOU looks better than this. This is most certainly console footage.
But the fire, lighting and overall smoothness in graphics and FPS suggests it's next gen.
Yes the TLOU looks great too, but it's certainly an exception, they did an amazing job to get it to look that great in the first place, using good artstyle, textures and tricks, people wouldn't have been surprised if it had been next gen.
Maybe this metal gear game is current gen, that's if the fox engine is that great, but I don't know why you say "certainly", it looks too good for that word, and we haven't seen enough footage to really compare it to TLOU.
