immi101: it's foremost the publisher's job to make sure all their customers get a chance to get/buy a new update/port. The store shouldn't have to run after them to remind them of that. ideally.
Sure it should primarily be the publisher's job, but GOG often gets neglected. It puts GOG at a disadvantage against other stores to the extent that it's affecting their reputation, so they should take some initiative regarding it (another big issue is GOG's lack of communication about things like this)
Writing an email doesn't take long and I'm sure that GOG have contacts at the developers/publishers that are much better suited to this & GOG are more likely to get results contacting those than we are sending emails to the general contact addresses posted on their websites (assuming any is posted at all, and assuming that messages to them aren't simply dismissed/ignored - most of the emails I have sent have not been replied to, especially in the case of the larger publishers).
Plus when I've previously contacted GOG asking about the missing Linux versions I've usually been told that they "do their best" to add Linux versions as often as possible.
immi101: If some devs/publisher are pushing the excuse that it is GOG's fault for not contacting them about it, that would be really, really weird. And all the more reason to blame the publisher, not GOG.
To be clear, none of the developers/publishers I contacted used GOG not contacting them about it as an excuse or blamed GOG in any way.
hyperagathon: Another Virtual Programming "port", ie WINE wrapper. Unfortunately, at least for those interested in these games, they've
reportedly once again dropped the performance ball. Rather disappointing, considering how well they did Bioshock Infinite.
It's not a Wine wrapper, but a proprietary one.
Anyway I had the games on Steam already from a bundle a while back, so I'm able to test them. So far I've only tested Saints Row: The Third.
Performance wise it seems comparable to Saints Row IV. Running the game at 1920x1200 ultra settings I was getting around 30fps in the city (some areas dropping as low as 22fps)... after turning down some settings I was able to get it to consistently stay above 30fps. Not ideal, but playable.

Edit: Just noticed that updates are out for both SR2 and SR3, will download and try those out soon. Edit 2: Doesn't seem to be any obvious changes in SR3 at least
