Last night's (August 18) airing of Warehouse 13 averaged 3.27 million viewers and a 1.0/3 (rating/share) with adults 18-49 or roughly 1.3 million adults 18-49.
The show has generated a surpising (to me) amount of ratings interest, but unless there are wacky production costs for the show, which seems very doubtful, it is surely a lock for renewal.
More thanks to @TVBill for the numbers. If Syfy puts out a press release with more detail, I'll post it later.
