Sit back, relax, grab some Erveluce and get your spies ready.
http://www.eurogamer.net/articles/2016-06-08-the-witcher-3s-gwent-set-to-be-a-standalone-gameCDPR just filed a trademark for the new logo and title "Gwent: The Witcher Card Game." We can expect an official announcement this E3.
Not sure how this will turn out, but there will need to be some major changes once you introduce human players into the mix. Spy cards will obviously need to be nerfed, for one, and I can see most players adopting the same cheap strategies or exclusively playing the same decks. Not a risk you can encounter playing NPCs.
Regardless, I can't say I'm not hyped for this. Even BaW didn't completely sate my gwent addiction. May also be fun if we can set up some tourneys here. PC would be the obvious choice, low demand and likely budget price.
