With only Akebono being unable to carry Daihatsu? This is weird.
The introduction of Toku Daihatsu may have changed a lot of things, you know.
After the introduction of Uranami, we thought that the fall event may be Leyte, or more specificly, Battle of Leyte Gulf.
From the hypothesis many of us also thought that the CA Kai Ni will be Takao, as she participated and survived Leyte.
We also thought that although Uranami and Kinu (now confirmed as the next CL Kai Ni) did NOT participated Leyte, it is possible for the devs to include Operation Ta-go (transporting reinforcements to Leyte Island), in which Kinu and Uranami sank, into the Battle of Leyte Gulf event.
But then, the fishing event gave us anti-installation equipment, and now the ranking reward gave us a new landing craft, while none of these are used during the Battle of Leyte Gulf. If the fall event is Leyte+Ta-go, this doesn't seem right.
However, there is a way to explain everything.
The fall event will be Operation Ta-go itself (known as the Battle of Ormoc Bay to the Americans), excluding the rest of the Battle of Leyte Gulf. Why does it explain everything? Now...
1. In KC transport missions are related to landing operations, and landing are one of the ways to attack installations. In other words, it is entirely reasonable for a transport-centered event to require Daihatsus and WG42s.
2. Kinu and Uranami participated the first Leyte transport (technically it is not part of Operation Ta-go, as it occured before Ta-go started), and guess who was with them? Aoba! Aoba was the last unmentioned member of the first Leyte transport, she was torpedoed en route the transport mission and dropped out of the mission halfway.
3. Akebono currently cannot carry Daihatsus, but she participated in the 4th Operation Ta-go.
4. Remember the escort ships, Matsu-class and No.1-class transports that has be long hinted to be introduced? They all participated in Ta-go.
As a conclusion, this is my new hypothesis:
The fall event will be based on Operation Ta-go alone, and the CA K2 will be Aoba. There is the possibility of Matsu-class, No.1-class transport, and escort ships being introduced.
