I'm currently usign Arch Linux, and I'm worried about what sort of installer each of the ditrobutions methods will be using. Steam will be using their typical installer, but what about the Laurian Vault and GOG.com. My preference is to get this game through GOG.com since I already have every single one of the Divinity games there and kind of would like to complete the collection. However if they are using debs, which I would suspect, that would be troubelsome for me.
The alternative is the Laurian Vault, which I suspect Larian will have a lot of control over. Will there be a shell installer?
[edit] Of course the Source code would be nice (so we aren't Hunting for it).
