Trilarion: I only see nine games there and you cannot even narrow down the search to DRM free but if you could it would be only four. However they have Linux although they probably do not offer support themselves.
So, I think from a neutral point of view GOG is hurting itself by not offersing some Linux support, if not much by means of actual sales then surely by reputation and also being an easy target for criticism.
They are surely not sleeping but they don't give the impression of being extremely agile, innovative ... ahead of the curve.
For improving the general situation regarding Linux gaming the new store is surely a step forward and increases the pressure on GOG to also do something. How much pressure exactly and if Linux games will ever come to GOG in the near future... remains a secret to us.
I think new HB store has different sales terms than their current store widgets for which they didn't have a centralized site before (all of them are collected here:
http://pcgamingwiki.com/wiki/Humble_Store ).
That's why you see so few games in the new HB store. It's basically a new thing.
As for GOG they may be not sleeping, but they aren't moving fast enough either.
JohnnyDollar: Maybe GOG will eventually come to the conclusion that it's in their interest to include the platform another year or so down the line.
That would be coming veery late to the table, so to waste go all GOG's claims about how innovating and ahead of the curve they are. If they want to compete, they need to do it here an now, not in a year down the line.
