Probably will upgrade armor eventually, but they need to make sure tome/crafted/raid gear is higher ilvl than Eureka armor. This is because Eureka Armor can be gotten in a few days but Tome/Raid gear takes weeks due to lockouts. So 365 armor will probably come out when tome/raid gear is 380-385. If it were to come out now, nobody would bother with i360 tome/crafted gear since why bothrt getting 450 tomes per week or doing 24-man when you can spam Eureka and deck yourself out completely?
