With how fast they are making this DLC I bet we will have Horizon 2 in 2019 easily now that their tech is locked in besides them doing some upgrades here and there over time. Unless they decide to go for a ps5 technical showcase for it, but I hope not because that dragged Killzone shadow fall down by being a ps4 showcase.The Frozen Wilds will be the only expansion for Horizon Zero Dawn.
