February ranking results will be announced this evening (3/27 JST). Top ranked Admirals will receive rewards, including new equipment that will become obtainable and improvable after the next maintenance.
The next update is most likely a Suzuya Kai Ni update, with Type 0 Fighter Model 63 (Fighter-bomber) fairy being Suzuya, it's speculated that Suzuya will become CVL or will be able to equip dive bombers.
Suzuya outright becomes a CVL, losing her abilities as CA(V), or is a CVL who also has the abilities to fight like a CAV, or the opposite where she is a CAV who can fight like a CVL. (Similar to Zara who is a pseudo CAV though having classification as a CA, and Abukuma who is a pseudo CLT but having classifcation as a CL)
Suzuya K2 is a convertible K2 (similar to 5th Car Div, Asashio & Kasumi), either being a CAV or CVL, depending on her Kai Ni variant.
Suzuya K2 is a CAV who can equip Carrier-based Dive Bombers.
Going to have to wait for more tweets for hints or just outright wait until April 5th Update :x
Great, obtaining M63 (FB) from Akashi's arsenal from the M62 (FB) is just BS and for the Kyoufuu Kai they'll need to increase the development rate for the Observation seaplane if it's required (if it's Shiden K2 then the development rate is fine as it is).
