From this Reddit thread:
Bolded what I felt were the biggest talking points.
-Eureka's first goal was to reanimate "Right after the launch of an MMO".
-Eureka will get an update in patch 4.3x.
-The next Eureka area:***** (Word will replace Anemos) will have a few new functions and game play elements added to it. (He hinted at something you can do solo as well)
-They are planning a levelsync system so players who started late can catch up (note: Not talking about the levelsync for NMs, but a levelsync you can use anywhere in Eureka)
-If they make it too convenient, Eureka will just turn into another/the usual FFXIV, so they will need to find a balance in between.
-The next hot fixes (planned for the end of March) will include some improvements to the game play and adjustments to the lock boxes.
-The hot fixes coming after the above hot fixes will include adjustments to "identifying Anemos crystals" to make it easier to turn Anemos crytals into inferior crystals.
-They will not implement a "deathscythe" in FFXIV. (TL note: a deathsyche is an item from FF11 with Damage:97 Delay:528 and was overpowered for a craftable "NQ regular item", meaning that it was as strong as top tier weapons for other jobs, even though it was easy to get and cheap on the auction house = market board. Deathscythe Hayashi = current lead item designer who got his name from the same item, was on the stream with Yoshi-p tonight, and to this day and after 14 years, people still remember him and his sins as the man who overpowered a scythe. For those players who haven't played FF11, just imagine the crafted ilv 320 (not 350) NQ weapon being as strong as the Kefka weapon (Ilv375) and only for dark knight).
