I have the feeling it's going to happen eventually. The guys who are dismissive of it haven't considered the passage of time, and how a new generation of anime writers/ directors may grow up on the Internet, and gradually become influenced by Western bullshit. I know many Japanese ignore or refute it now, but I have this idea that there will gradually grow an enclave of Westaboo japanese thanx to the influence of the Internet (and the fact that many cultural commentators on Jp and/or anime are now fags) who are seeking more 'progressive' values.
There seems to be a vague nudge in that direction even now: https://www.youtube.com/watch?v=eByb9s4InaA
