EnforcerSunWoo: People need to seriously taper their expectations. While I found this stuff and it is very much linked to GOG, it doesn't mean that this stuff isn't going to take weeks, months or even years. Even to the point of found games such as Assassin's Creed II through III, Rage and Skyrim; those never did arrive here after someone happened to find evidence of them. So while the enthusiasm is great it also doesn't mean that we are necessarily getting anything that I happen to find.
True. But some of what you listed is from recently-active publishers. I personally won't be too disappointed if they don't show but Vanquish and
especially LEGO The Hobbit strike me as safe bets. (On Steam I see LTH and DLC for it, but no "Complete" bundle of the two which I find odd.)
A Dead Island release, I suspect, may depend on to what extent GOG thinks people will or won't buy it if multiplayer is missing.

I'm skeptical of that. I personally don't care if multiplayer is gutted from the GOG release, but obviously I'm just one person etc etc. (Techland's Chrome and Specforce strike me as even easier "brings", unless there are some legal issues of course.)
