I keep wishing on that myself, but PoE2 apparently didn't sell more than 500,000 copies and I think I read around that for Obsidian it wasn't really a financial success, and at best, it just covered the costs of making it.
We'll see I suppose, at least now they're not at risk of dissolving if the game fails, as they're working with Microsoft's wallet. They might still get dismantled/repurposed if they don't pull their weight, though.
