Nice to see Capcom on board. Unfortunately, you only need to look at Steam's Japan store to see how small Capcom's offerings could be on GOG. I.e., no Resident Evil, only one DMC game, only one Lost Planet game, Flock!, Age of Booty, and more SF DLC than any sane person could ever want.
Capcom won't even publish Japanese games for which they have the Japan distribution rights as they, and I quote Capcom, "don't care".
Now, I would love to see GOG actually persuade Capcom Japan to sell all PC games via DD on GOG and thus prove me wrong, but other publishers who have joint rights with them have failed to do that for all other major DD stores already, due to the aforementioned "don't care" response from Capcom Japan.
