Toukiden 2 will be out Spring 2017. Koei Tecmo did not disclose the platforms, but if you inspect the elements of the Toukiden 2 webpage, it actually lists the platforms. Open the first tree, and it says this:
<html lang="en">
<head prefix="og: http://ogp.me/ns# fb: http://ogp.me/ns/fb# article: http://ogp.me/ns/article#">

<meta name="apple-mobile-web-app-status-bar-style" content="black-translucent">

Most likely, it'll be out for only the PS4 and Vita. The PS3 version won't be localized.
