mistermumbles: "Everybody onboard the unrealistic-expectations-hype train!" All I can see is a bunch of future sad sods who had some severely delusional optimism. Capcom, anyone? =P
I don't know. Is it too much delusional optimism to have Namco release heavily-discounted and bundled stuff like Pac-Man, Inversion, Deadcore and Enslaved? Not to me, at least. Besides, GOG isn't the site it used to be back when Street Fighter Alpha 2 was released.
mistermumbles: Grargar's comparison how Paradox debuted on GOG is also not really a good example as Pillars of Eternity was already promised on GOG before Paradox even entered that picture. Sure, Bandai Namco's debut with a more indie-type title might slightly increase the chances of their big titles appearing here, but I wouldn't bet on it.
In that case, Pillars of Eternity could have been released self-published; it didn't and after its preorder announcement (and before the game was even released), there comes Paradox with some of their not-so-highly-requested games.
Do I think that Namco will be coming here all guns blazing with Dark Souls 3, Dragonball Xenonverse, Tales of Zestiria, etc.? No, but they could always begin with something small (like the games I mentioned above).
