I mean it's also easier on Steam for developers. a while back Valve added some stuff to Steam to allow developers to set their own sales whenever they liked, sidestepping the usual collaborative process.
could be the publisher probably heard about the sale and just wanted to get in on it and so had someone make the changes. I'm not certain gog had a ton of planning going into this sale. I think Valve has paying some attention to people working things around them. could also be the skeleton crew left at Runic were the pointmen on doing it. Runic always had a pretty near relationship with Steam.
even if gog had this sale planned well in advance, like I said, it's quicker on developers and publishers to do this stuff since Steam rolled out those changes. on here, the publisher would have had to go through the process with gog, and maybe they're not putting all so much in the way of resources behind the titles of their closed studios now.
