Season 1 and 2 are currently available on Hulu, so I suppose it shouldn't be a surprise that season 3 will be as well.
Those in the UK are already enjoying season 3, which began airing on channel E4 at the end of October; and according to AOLTV, the third season of the quirky, vulgar, smart teen dramedy Misfits will premiere on Hulu for stateside fans of the series (and I know several S&A readers are) on December 19 (a Monday), with all new episodes every Monday.
Recall Emmanuel's post a few weeks ago about a potential stateside remake of the series for American television; no further word on where that stands.
