I hope I don't disappoint you guys too hard, but the twitter did NOT mention that her K2 will come in 5 Apr.

本日月次作戦の武勲褒賞として配信される【新装備】は先行実装です. 次の改二改装で実装予定の樺太を流れる川の名前を由来に持つ艦娘、その改二改装関連の新任務などで獲得可能となります. また、次回以降のメンテナンスに伴うアップデートで、それぞれ「装備改修も可能」となる予定です.

The new equipment added as a ranker reward are pre-release. They will be available via quests, for example, the K2-related quests for Suzuya, the next girl receiving K2.

It's "the next girl to receive K2" not "the girl who will receive her K2 in the next update".
