Shows like John Oliver could go 20+ years easily. If he’s happy and making the exact show he wants to make, I don’t see why he wouldn’t keep going. Bill Maher is on season/year 21. And it really can’t be that expensive compared to their other tent poles.
I’m not sure if you have checked out WoW lately, but it’s actually a pretty beautiful game. I think generally they want the tech specs to be a low barrier to entry for a game where they want millions of players playing concurrently. It also cannot be super heavy or things like raids and battlegrounds would chug.
