Doubt it will be i240 cause that pushes into raid area too fast. I am hoping for about 3 steps starting easier and going up in grind from there. ie, get the quest, i215, do a bunch of things that take time(1 week ish) i225 and last the grind going to i235. Makes it above the i230 lore weapon we can start to get in 8 days but below the i240 upgrade. Nicely balanced for grind between lore and raid until patch 3.3. Patch 3.3 would be the next step to i245 which was what they did back in 2.xx series around 2.3x with the nexus grind finishing before 2.4 when fcob came out and scob was unlocked. Letting you start fcob with a t9 i115 or relic nexus i115 weapon.
In the end I hope there is some content in 3.25 to do like the start of relic in 2.0 with Hydra, Chimera, Ifrit, Garuda and Titan.
