First part is a translated Chinese Q&A, so take it with a grain of salt. Source: Horizonwalker, NA.
Developers have regretted their decision of not implementing submarines. Right now they are looking for a way to introduce submarines to the game, however everything is uncertain at this point.
Developer Ev1n denied this and said that submarines won’t come. Translation mistake.
-German tier X battleship’s guns are still subject to change, in other words, they may change them to 406mm gun instead of 420mm.
-If everything goes okay, German battleships will hit the ST in patch 5.9 and release in patch 5.10.
-They may buff US CV’s fighters.
-They are not going to overhaul the economical system in game right now, but they may indroduce spotting damage (with earning) in the future, and they are still aiming to improve high tier economy.
-Dunkirk will be released this year.
-It is more fair to have a +/-1 MM, however this will make game less fun, so if you are looking for more balanced games, go play ranks. (eh, but there is no rank mode in Chinese server ) In the distant futue, if the game is mature enough and have much more players by then, they will consider +/-1 MM.
-The problem of Tone is complicate. They will release the Tone after they develop a new mechanism for aircraft cruisers.
-Kitakami is the only ship that deals more damage to allies than enemies, therefore they removed it from live server. It may become a reward for skilled players in the future.
-Apparently, second Japanese DD branch has more priority than US CL branch.
-The goal of their development, is to add every famous WW1/WWII ship into the game, thus German carrier Graf Zeppelin will be in the game, not this year though.
Second Q&A (From Carnotzet, EU):
1a. Are German BB’s still planned to be released during Gamescom ?
A. At the earliest, they will go into production-testing in the next update. After that, we’ll see.
1b. Will Flint remain the final reward during for all seasons or will it change at some point ?
A. In the short-term (two to three seasons), the final reward will remain Flint.
1c. If I recall, bastions are equipped with 40.6 cm SK C/34 canons, right ? Are they the same as the upcoming German BB’s ? And will their characteristics change along those of the H-class guns (if changes are made to them, that is) ?
A. Bastion cannons characteristics are set solely on balance reasons, without them being tied to other weapons.
1d. In reference to your (or was it you?) last statement about the fate of Cleveland, some players started to fear that the US light cruiser branch was abandoned and that we should not expect it anytime soon. Or could you build one without Cleveland ?
A. No, we haven’t abandoned it. We have the desire to clean up cruiser lines and generally work some more on the existing lines (maybe add a new branch, adjust the tier of a ship, etc.). However, we’re currently not working on this since we have quite a lot of work with the next few updates.
1e. When you released the Soviet cruisers, there were high expectations for the top ship, Moskva, in regards to how similar ships would fare in the game. Did she meet your expectations ? And will you add Stalingrad or Alaska ?
A. Moskva is a good ship. I can’t comment on unreleased new ships.
1f. I remember developers promised to release four new branches this year. Currently, only one has been released, one is soon to be released, and about the remaining two, we haven’t heard a word. Do you intend to keep it a secret for long or will you tell us to wait and see ?
A. In a video, we promised two lines. As far as I can remember, JamesWhite said on a stream that there may be 3 or 4.
1g. Are you happy with the ramming mechanics ? Logically speaking, it doesn’t make much sense.
A. Yes, we are happy with it. We could make it more complex but it is very low on the priority list.
