Ok as a reminder, today will be when they will do maintaince/ update thier game. So get what you can before 11 AM Japan time.
As far as I know, so far I know that this update will definitely have the following:
They will be tweaking the item section of the user interface to properly display the number of items at higher value. Up to the 1000s I think.
Hina Matsuri has come to a close long back, so the furniture associated with it will be gone today! If you really want it, go get it while you still have a chance!
Ship space limit (for those that purchase the extra space) will be expanded from 180 to 190 with this update.
Also it's been confirmed we're getting a new ship girl today!
As for Kirishima, she might get her upgrade today. Though I haven't heard or noticed more talk about it. So I'm wondering if they're going to add her in this update or not.
Also from a recent article that was published in Famitsu magazine. One of the devs associated with Kancolle discussed several things regarding the game, the VITA game (which has been confirmed to be a strategy game of some sort.) And talked about who will be getting Kai 2s soon.
The following was hinted:
1. The last of the fast battleships will be getting an upgrade soon (We know this is Haruna already)
2. A light cruiser who bravely fought in night battles and provided AA defense for her destoryer Squadron. (This is likely
)
3. A pair of reconnaissance ships that were also hybrid cruisers will be upgrade soon. (This is reffering likely to the
)
We don't know when these will be released. (Other than Haruna who has been confirmed to be put in for the first Anniversary update) But I will say again, get these ships prepared as soon as you can.
Also the Event that is being planned will start likely around the week of the First Anniversary of Kancolle (So probably near the 23rd)
