There's NO WAY they will add it to existing games considering the amount of resources doing something like this takes.

I don't see why any game like this shouldn't have the option there, you don't have to tailor make it for multi, but let me and a friend play it.
Because adding multiplayer always adds lots of additional work to the game. You have to add the functionality in the first place, beth games don't have anything like it, you have to add some sorta matchmaking, or server system. You have to add balancing to the monsters (do you double the HP? What if there's player mismatch in levels?). You have to add XP and loot balancing. Do you have first person to grab get the loot (diablo 2 style) or everyone get own loot (diablo 3 style)? Is it all balanced now? Have to test it tons more to make sure it all still works and can be finished with and without having a friend. How many friends do you let play? 2? 3? More? Now thats more testing needed.
If it was easy or at least doable, you would have seen mods do it in previous beth games.
