Hm... Depends. Last time I wanted more episodes NOWNOWNOW!!!! In the end I became fatalistic and accepted that I had to wait. It might be the same after this season. I wasn't really nervous about S3 until maybe a day or two before it started. The wait had been so long that my passion with the show had grown a bit cold.

There will be a season 4 but who knows when? I think they first confirmed it at Comic Con.
