I'm not sure if there is an exact release date for Season 2 yet, but for sure there will be a prequel most likely airing in January which will tell us all about the House of Batiatus before Spartacus arrived and will give fans a chance to see crazy Batiatus again. Season 2 was delayed due to Andy's illness so hopefully we may see it sometime around summer 2011. Here is some news on what we can expect on the upcoming shows:
Latest news (from the Panel Tweets by Spartacus_Starz and Moryan) about Season 2:
DeKnight: Slave rebellion in S2.It will get bigger & bigger as season goes. Battles will be outside gladtr arena but lots of that in prequel
In S2 Spartacus will start to see big picture & become more socially conscious. More than just his revenge. But he'll still kill lotsa pple.
DeKnight: "I'm a huge romantic," cites Crixus/Nevia, Lucretia/Batiatus etc. Will be lots more of that in S2 - relationships, love etc.
Whitfield wants to pack on more mass for S2. In 1 he was about 185-190lbs. Here's to a 200lb Spartacus in 2011!
