The Tokyo Game Show has disgorged a new trailer for Horizon: Zero Dawn and it contains a lot of new footage including the Earth before it is devastated, and the the younger Aloy in action. There also seems to be a rather large plot spoiler about where the corrupted beasties come from, so maybe stay away from the trailer if you want surprises.
Of course there is the other question of: What is this running on? It looks stunning, so presumably a Pro. Eagle-eyed viewers will also spot what appears to be pre-order costume DLC at the end.
