Well Rain World is coming to PS Vita and PSN, and the devs have hinted at "big console news", so I wouldn't be surprised if more games get console releases as well
That's the developer bringing Rain World over themselves though, isn't it? (Actually, AS Games' presence in promoting or representing its titles is in its own way quiet; same thing with Volgarr, the official web page doesn't even mention AS even though the Steam release is repped by ASG; the Xbox One version seems to be self-published, I'm not sure where ASG fits in?)
I'm talking Adult Swim Games actually making a partnership to bring its lot to consoles, or a console. I just feel like that would be a nice, cool thing to see real big on an E3 wall with the great slate they have.
Another option would be launching an app on web-friendly consoles, of which I think they all are, for playing a host of their web games in HTML5-based form. (Though unfortunately even their newest stuff is Flash-based on the website so it sounds like that's a lot of conversion; on the flipside, a good portion of their games are button-based instead of mouse-driven so that's adaptable.) Their full-spec games like Oblitus and Zenzizenzic would still be produced as downloadable products, but they're launching new web games all the time, and getting those approved as downloadable games (especially the licensed product, which often comes out quick to capitalize on a phenomenon) would take forever even if they tried to give them out as F2P. One app (or maybe two apps, since AS Games and Cartoon Network Games exist in tandem, I don't think CN Games has the same cache of quality but it does have some name brands) that is constantly spitting out new web-applet games to play on your TV would be a good little offering.
