Partly glad because I don't have the resources for that kind of levelling right now, but also kinda bummed because they're kinda in need of a K2.
They had their "Hope" when no historical hint was given out for the BB Kai Ni at the time
I was hoping for some speculation about thoses two's Kai2, just to see how outrageous the Devs can be to add "TOO MUCH K2 in such a shot period of time, I can't follow them and make K2 them Day one, must kill myself waaargh" fuel there...
Then, I remembered that Ise & Hyuuga have already been seen on a "Big" equipment before, the Type 32 Surface Radar Kai, and that thing was released a long moment ago.
That 46cm triple gun mount Kai likely wont be stock equipment for Musashi Kai 2. Just look at Nagato Kai 2, had 41cm triple gun mount Kai in CG art but dont even have any as stock(she get proto 41cm instead)
Either way let's see how things unfold (Next thing to wait for is Comptiq March 2018 Issue released on Feb 10th to see the next KanColle Special Issue)
Maybe USN Gambier Bay is coming?
Devs clearly stated the 46cm Kai is NOT Musashi Stock Equipment, and that she will get a different Main Gun Equipment.
That would be downgrade from her basic and kai forms, which come with stock 46cm.
Tatsuta had quad oxy torps upon Kai and then the oldest torps possible upon K2.
While it's valid reasoning and these torps were historical + hinted to be Akashi matherial for something (hopefully) more useful, I dont see why devs cant pull something like Proto46 on Musashi (worst case - another 46 bc devs said it wont be 46 kai so at least P46 would be nicer)
That smile on the damaged CG of Kisaragi
