Summon Night 6: Lost Borders will be localized by the Gaijinworks and released on PlayStation 4 and PlayStation Vita in North America, South America, and Europe in early 2017.
The company has announced on their official website that it was all because of fan support of Summon Night 5 that led to the decision. Additionally, they write this about the game:
Summon Night 6: Lost Borders weaves an emotional tale of friendship and discovery that begins in the sparsely populated “cocoon world” of Fillujah, where the three main characters (Raj, Amu and Ist) live in virtual isolation. Each has a single companion, a flying sidekick with an amazing special power, and they are all surprised when dozens of strangers begin to suddenly appear—literally falling out of the clear, blue sky. Lost Borders can be played and enjoyed without any knowledge of the previous games in the series, but fans will recognize that the mysterious strangers are actually returning characters from all of the mainline Summon Night games.
Summon Night 6: Lost Borders is coming to PlayStation 4 and PlayStation Vita early 2017.
