I agree completely. From an emotional perspective, probably most of us (myself included) think it is unlikely to see such things happen, but there is nothing absolute and impossible about it. Just a short few months ago people thought it'd be completely and totally impossible to ever see any Bethesda games here, and now we have several. There was Warner Bros. before that, Lucasarts before that, and others.

Likewise, Microsoft criticized Linux and open source software as being heathen communist software for years, attributing all sorts of horrible statements to it. Now, Microsoft not only ships various open source software themselves, but they have contributed some large chunks of code directly to the Linux kernel themselves, and they now have their own Linux distribution and are releasing more and more pieces of software as open source. The take home from that, is that Microsoft painted themselves in strong opposition to open source and Linux and now it just makes good business sense for them so they're backpedalling on that and embracing Linux and open source a small but increasing amount.

What it really boils down to in the end is not gut feelings or emotions at all but business decisions. If and when a company thinks on their own terms (not dictated to them by 3rd parties) that they stand to make money from putting their games on GOG.com, and they're able to figure out a way to do this in a manner that is acceptable both to themselves, to GOG's requirements, and to any legal agreements they're subject to, then there is a chance that they may decide to bring their games to GOG.com too. Of course in many cases that would involve spending some engineering on some games and that needs to be taken into account to whether or not they feel such an investment is worth it for a projected return-on-investment. But it does happen as we've now seen many times, and I think this will become increasingly common in the future as GOG gets bigger and attracts more companies and the Galaxy platform matures and offers more feature parity with other platforms.

I think such is ultimately inevitable, the only thing I/we don't know is the time frame, and we're inclined to think of time frames for things like this in a way that if it isn't currently happening visibly right this instant - then "it'll never happen". But alas those are just emotional responses that don't ultimately have any weight unless someone has a functioning crystal ball. :)

Aside from all that though, GOG has been talking to Microsoft for a long time now and I'm sure something will eventually come out of it. With the introduction of the Lucasarts Star Wars games here, hell has already frozen over, so I think it is reasonable now to think that some day we'll also see pigs fly too. :)
