Yes, there will be a Season 6. There is also discussion of a Season 7.
Not sure how much further the story can go, but I would watch anything with Gilfoyle, Dinesh and Jared. Occasional Big Head and Jian Yang is great also.
Would like to see them really hit it huge.
I would have been satisfied if the series ended here. I mean, after five years and all the starts-stops, they finally succeeded - and essentially slayed Hooli and their Chinese competition to boot. Where do they go from here?
