So if the Relic doesn't get to i405 in Pyros, it's possible that a final area will be implemented for the final step...
It's doubtful to me that we'll get a "victory lap" of content outside of Eureka for the 4.0 Relic, but I guess they could do a Victory Lap that requires you to go through all the Eureka areas and kill specific FATE targets with your 4.0 Relic equipped... /pray for those that have to defeat Cassie... If such a Victory Lap is a step in the 4.0 relic, then a 4th part of Eureka would be unlikely.

Per the official blog: "These can only be used in Pyros and the next iteration of Eureka, but you'll be able to use them as soon as you enter Pyros!"
