The next second remodels to be introduced should be the 5th carrier division, which should come either in 25th September (when Zuikaku was completed, is a Friday this year, when most updates happen) or 23rd October (one day before the Battle of Leyte Gulf where Zuikaku sank, also a Friday). So just wait for a while longer.

Why not Shoukaku? Because all Shoukaku-related dates this year had already passed, except 12th December (when Shoukaku was laid down in 1937), which is way too late compared with the devs' announcement of "around this summer".
