A new Russian language interview with GOG seems to point towards upcoming GOG releases for Paradox's
Tyranny as well as Telltale's
Batman, if the machine translation is accurate:
"Classic is great, but many people would like and something fresh. Oleg Klapovsky, admitted that for this part of the GOG has had some difficulties. Progress, of course, is: over the past year in a third directory Witcher, Divinity: Original Sin, Superhot and other games. In the nearest plans — Master of Orion from the Company, space simulation No man's Sky, the Tyranny of Paradox game and Batman series from Telltale."
"Классика — это замечательно, но многим хотелось бы и чего-нибудь свежего. Олег Клаповский признал, что по этой части у GOG есть определенные трудности. Подвижки, конечно, есть: за прошедший год в каталоге появился третий «Ведьмак», Divinity: Original Sin, Superhot и другие игры. В ближайших планах — Master of Orion от Wargaming, космический симулятор No Man’s Sky, игра Tyranny от Paradox и сериал о Бэтмене от Telltale."
