Link Console Gaming Accounts to Profile

Can linking to Xbox Live Gamertags, PSN Profiles, and Nintendo Network IDs be implemented at some point in the future? If more games are getting released on consoles (such as Dungeon of the Endless was), it might be reassuring for users to know their achievements might possibly be tracked by Games2Gether's site for the sake of badge progress without owning the same game on Steam.

Unfortunately, I don't know if tracking game activity via achievements and trophies would be better or worse than implementing some sort of Games2Gether in-game login instead. I haven't kept up with any of the gaming consoles' APIs over the years. The only companies I've seen implement this do still require players to sign-in in-game (Bioware and Ubisoft).
