This is a brief summary of what Global players can expect to see within the next month for FFRK.
First of All, Next week is most likely going to be the release of the first Story Update including all new classic dungeons from FFI, FFII, and FFVI.
New Playable characters from the update include Cyan (FFVI), Josef (FFII), and a few core class characters like Summoner.
Quickly following that, a new Event will come out. The most likely event will be Terra's Event, which is a Completion style dungeon such as the Shinra Event, and the Mt. Ordeals Event.
Notable Rewards include the Playable Character, Terra, and some FFVI accessories.
The Difficulty of this event will be a little bit harder than the Shinra Event, but nothing too out of left field, should be easy for anyone who's able to clear "Countdown to Destruction" on the Hard difficulty.
The week after (Heading into May) is most likely going to the Celes' Event. This is another new type of Event called a "Survival Event". Differing slightly from the Collection Event going on right now, you will receive medals after clearing stages. And after reaching a certain number of medals, you will receive a reward.
Notable rewards from this event include, the Playable Character, Celes, 4* and 5* Ice and Holy Orbs, and quite a few 3*+ weapons and armor from FFVI and FFVII.
This will be the first difficult event and will actually be a challenge for people with average levelled parties (40+ may still find it a bit hard). Death in this event is commonplace, and will come at often random times, SL quite a lot.
Following that, in the middle of May, we should get our 2nd Collection Event, which is Lenna's event. This event will be similar difficulty to Celes' event, so Watch Out!
Notable Rewards include, the Playable Character, Lenna, Mythril, a chance to get 3, 4, and 5* orbs for much cheaper, and some FFIV gear.
Rather than Countdown to Destruction, this Event will have FIVE difficulties, rather than 3.
Around that time, should also be another rather large story update, updating FFI, FFII, FFIV, FFV, FFVI, and FFX, and introducing FFIII, FFVIII, and FFXIII into the game. New Playable Characters Include: Gordon (FFII), Luneth (FFIII), Warrior of Light (FFI), and Snow (FFXIII)
Following that, right around the End of May, should be Rinoa's Event. Which is another Completion style event.
Notable Rewards are unknown other than Rinoa being a reward for beating the event.
