Yeah, there are going to be some massive changes within the Japanese game industry within the next couple of years mostly because Kojima is right, they're lost. Asides from a few select developers like Nintendo EAD, Level-5, Team ICO, and Kojima Productions, Japanese game development has become really stagnant. Square-Enix is the best example of this.
I think we're going to see major mergers within the Japanese video game industry like the Konami-Capcom one rumored many years ago, Japanese companies acquire more Western developers like what Nintendo did with Retro Studios, Sony did with Naughty Dog and Media Molecule, or what Square-Enix did with Eidos, and some just flat out shut down.
