That comparison is really frightening me right now, with the current world situation... at least the two old men of the studio have their reputation, but... what will happen with the new generation without the name of those two attached to everything? Scaling back the type of productions they make after the more immediate following projects seems reasonable enough... that or disbanding the studio.
They could always just peddle merchandise and reap the benefits of an extensive catalogue after Miyazaki and Takahata are gone. Become a company dedicated to the memory of good projects, rather than the production of them.
