Resident Alien - season finale or series finale?

I just watched the last episode of Season 3 of Resident Alien and found
myself wondering if that was a season finale or a series finale? They
certainly resolved *some* plot lines but other things were left
dangling.

I'm trying to find Robin's post where she laid out this week's TV
viewing and came up empty, thanks to the many weaknesses in Claws Mail.
She normally says if something is a series or season finale.

Futon Critic says it hasn't yet been renewed for a fourth season, which
makes it sound like a fourth season is at least possible. Does anyone
know if a fourth season is desired by the producers or has everyone
already gone their separate ways?
