There is no news on a season 3, and as previously stated, there probably won't be for a few years.

The author still hasn't finished book 11 (the web novel hasn't been updated often in the past 6 months), and season 3 would be books 11-15. It's probably still several years off. When there's news, I'm sure it'll be prominently displayed on the wiki and on LogHorizonFunFacts Tumblr blog (and many other places).
