In a recent report with GamesIndustry.biz, Square Enix's CEO Yosuke Matsuda had a chance to discuss about the current state of the company's output in the west. Matsuda clarified the impression of their Western titles' seeming decline; the publisher's Western RPG series in particular, which is Deus Ex, has knowingly met a less than satisfactory number of sales with their latest entry Deus Ex: Mankind Divided. If you were worried about the series' future based from this, however, Matsuda claims to push your worries aside as the next Deus Ex installment is actually being discussed within the company.
Deus Ex's future plans have been pretty quiet, but that's only because Square Enix's Eidos Montreal is busy working on several big titles at the moment and everything needs to be in accordance to their development lineup. Matsuda continues on to say that Square Enix considers Deus Ex as a very important franchise, due to its unique position to their library of titles.
