JaqFrost: Well, it should be fairly obvious by now that GOG is pro-regional pricing. It was pitched as a benefit to the consumer -- we'd get AAA titles, hallelujah! -- but sounding suspiciously like something they were very eager to implement. Regional pricing means more profit for GOG, particularly once they can get rid of the fair pricing package and they, like any business, are in this for the profit.
Means more profit for them either way. They get well-selling (just see the front page chart, outside of sales which skew it) titles that they make full profit for in case of non-EU/AUS sales, they draw EU/AUS customers from other platforms, which customers may buy other stuff as well after they get here, and they do pretty much break even, maybe even make a marginal profit depending on exact taxes and transaction fees, on EU/AUS sales even with the package even if the customers use the credit for something else right away, and if they don't use it right away then they get the use of those extra money for a certain amount of time before eventually paying them when the credit is used (and still breaking even as a result).
In a business sense, as long as they draw more customers with the package than they lose due to having regional pricing at all, I'll say they'll keep it. And they're rather running out of customers to lose because of it, probably.
This, of course, also means they have little reason to ever struggle get rid of regional pricing, even on a per game basis I mean. It'd help them not to need to cut that profit anymore, and of course even more EU/AUS people would come if the games would actually be cheaper instead of getting the credit for the difference, but since as of this year it's obviously money over principles, they won't risk losing games for it again.
As for the devs, I did see two indie devs posting in confusion about the regional pricing thing, and a post from Cinemaware that somebody linked to where they seemed to be saying that they just accepted the pricing offered to them (which GOG was quick to deny, but... right...). However, for the one regionally-priced Cinemaware game, as they said themselves in that post, they were not the publisher, Kalypso was. So that does seem to be the deal, and that is usually the deal really: Devs have no say in it. Like those two I saw posting said, they just want to make games and not worry about finances, so they go with whatever is suggested to them by publishers, shops or whatever other services they use. And most publishers definitely push for regional pricing. Whether GOG offers it as default now the same way Steam does, remains to be... proven.
PS: By the way, does anyone realize Skyrim would as of some 2 weeks ago fit the original GOG mission statement, of a good game at least 3 years old? I'm not seeing that here, with or without regional pricing. Hell, not even seeing some patched versions of Arena and Daggerfall, which are freeware.
In fact, after they said they'll allow newer games and games costing above $9.99, in 2012 I think that was, and introduced that new GOG with Assassin's Creed and HoMM5, what else did we get of that sort?
