The future of Playstation in the Japanese market is gonna be interesting for sure, they are on a massive decline over there as Nintendo's marketshare continues to grow. Plenty of Japanese developers/publishers like Koei Tecmo, NIS, Marvelous are treating the Switch as a sort of Vita successor by at least most of their titles for the system. They are even getting their games like Disgaea 6 and Ryza 2 reveal during directs despite their series much longer history with Playstation. Even loyal third parties developers like Falcom have licensing out almost every game they made for the last 5 or so years to get a Switch port. Sony needs to do something about their hardware and software sales in Japan otherwise they might actually end up in a situation in a just a couple years where a lot of loyal third party Japanese developers either go full multiplat or worse for Sony full on Nintendo exclusivity.
