You beat me to it! Anyways, I'm glad to hear more about the details for this game. Sounds like the timeline for VIII is set between Ys V and VI, he visits Xandria in Ys V and Eresia is the place he explores in VI. I also remember the details about adol having to build a base which is an interesting twist for the Ys games. The release date for the game has been revealed for Japan already, it's targeted towards a summer 2016 release.
To back up my statement about the 2016 summer release date, here's an article about it.
