就之前的情报来看

推测是外设 搞新玩法之类的

要卖2000万没有搞流行可没办法

I believe Emily confirmed it'd be Thursday.
Hey, there's always a possibility that this announcement might drop earlier than Thursday.

Plus, it's 7:00 PM in Japan right now. It will be Thursday there very soon.

My only expectation with this announcement: Some type of software that uses accessories, devices, or add-on hardware.

Beyond that, I'll admit, I don't know much about what this is.
