Riot Games

I know league is still one of the number one games out there right now, i was just curious as if Riot had anything else up there sleeves. i mean it is Riot Game(s) after all, also this page http://www.riotgames.com/our-games has been so small for so long i was just wondering if anything was going to get added to it any time soon. Haven't played League in forever, don't hate the game; still quite fun to watch friends play. Just asking a question.
