I honestly can’t decide what would be worse for profits. The mod update is hugely well known.

Given the atmosphere around just about everything corporate, I feel they should take a small loss here for the brand and release alongside the mod, or after it, or whatever. Good PR move that should make people want to buy the game in good faith.

The only issue is this is Oblivion. That’s a dedicated fanbase only beaten by the rabid battalions that want another Morrowind.
