So this is just further 2nd Hand Info someone else who can read JP dug up from the documents, but apparently the new studio cost 14.3 million USD. Just to acquire the location. They plan on spending another 6 million USD to furnish it with necessary equipment. So more than 20 million USD for the new studio. Additionally they want to spend several millions to upgrade various stuff in their Headquarters as well.
Also, going by those area numbers, this studio is 70x70m large. The current studio is 824.80 ㎡ large, so the new one will be 2,5x as big. You could possibly have several stages in there and record multiple things at once.
This would adress the biggest concern that I had with Cover, that everyone wants to do more 3D content but they dont have the capacity to do so.
