Earlier this year, it was reported that Square Enix put the Deus Ex series on hiatus after underwhelming sales of the latest entry, Deus Ex: Mankind Divided. It's not true that the series is going away forever, Square Enix CEO Yosuke Matsuda said in a new interview. In fact, plans--at least preliminary plans--are already underway for a new instalment.

"We have never said anything about discontinuing that title but for some reason that's the rumour out on the market," he told GI.biz in a wide-ranging interview.
