I'm willing to bet that for the most part we only see Bill, Miyamoto, and Reggie in these directs.
And it's awesome that they are going to continue. There have been several games I was waiting for that had been announced recently. The Micro has the announcement that Bravely Second would be localized and a Chibi Robo reveal. The one before that (besides the dedicated Directs for Splatoon and Xeno X) had the first sneak peak of Xenoblade X with english voice acting the the announcement that Fatal Frame V would be localized. But even when there is absolutely NOTHING I care about, they still are very entertaining to watch. Would be exciting to get some more info on LoZ and the first Wii U build of Pokken. Now that Mario Maker is out, and Xeno X as well as Fatal Frame V has already been released in Japan, it will be interesting to check out the japan directs too (due to the fact that they will have to be different).
