Its doubtful zos will make the next 2 years let alone 30. Things are changing and games arent a priority at microsoft anymore for reasons. The game has made some money over time but is still a generally poor performer. It wont take much for the axe to fall again. Theres no point to upgrade the engine when you can see the sun setting. If i was workin at zos and i wasnt in the protected crowd id be moving on lol. Not that theres anywhere to move on to.
