Aside from the special edition content, there's every indication that what's here right now is mostly the final game. There will certainly not be any additional deities or glyphs, and it's very unlikely that there will be any additional classes or races. There might still be additional items or dungeons planned, and there's indication that additional quests are still planned, but only the devs can speak for that with any certainty.
What we do know is that development has yet to really begin in earnest on the puzzles, so those are still forthcoming.
