It was a tossup whether the Invincible class was going to be armed with 9.2in guns instead of 12in weapons historically. With Fisher pursuing balance rather than the extremes, it's almost certain they'd keep going with the lighter weapon.
That means that the Germans will persist with the Blucher's basic design instead of going to the 11in on the Von Der Tann. So basically, a turbine powered Blucher.
The big question is whether there is less pressure to develop the problematic 12inL50 weapon or not.
