For those who missed the conference, you were probably lucky. Pretty boring like most Japanese conferences usually are, went on for a whole 2 hours too!

Sony said at the end of the conference that they know the Japanese gaming industry is way behind and that they want to change that, and will be making bold and strong moves to help recover the Japanese game industry on consoles. I don't think they'd say such a thing if they didn't mean it. From the announcements shown it shows they are taking things quite seriously.
Also the Destiny bundle was announced for Japan along with a silver Dragon Quest themed PS4.
Nagoshi is proud to be a PS4 supporter it seems
