Bethesda are so chill about Skyblivion that they're promoting it in Oblivion Remastered videos

Why not? He's the development lead at Bethesda Game Studios who has worked there for 20 years.

Bethesda gave the Skyblivion team free Steam keys for the Remastered version. While I agree that we should apply skepticism, actions seem to demonstrate that Bethesda itself is cool with them, so I think it's probably appropriate for any one team member to speak on their behalf as a whole in this regard.

While you are absolutely correct in your skepticism, id like to add that multiple facets of Bethesda have both implicitly and explicitly either condoned or outright celebrated what the team is doing.

This project seems to not only just be on Bethesda's radar, but they view as a good thing.

But they do sometimes

One that will be succeeded with a next gen update.

Probably Special Edition or above
