Fallout vs Diablo TV series?

With the success of the Fallout series who would watch a Diablo series? Would you base it off D4? D3? A mixture of the two? Who would play Deckard Cain?

I’d throw it in the laps of the people who made the Fallout series. Maybe not perfectly faithful to lore but I thought it was epic and ticked a lot of boxes. My only moment of annoyance was (spoiler)the “They fly now” moment with the T-65 armor without jetpacks.

I contemplated posting this on D4 forums but that would require me to buy the game. Is it odd that Fallout is what finally made me consider buying D4?
