New seasons of TV shows....how long?

Hey all. Im wondering if anyone knows how long it will take for the new seasons of Battlestar Galactica to start showing up in the iTunes store?

I thought it would be like last season where they showed up the day after airing.

I'm paying a HUGE amount of money just to watch one show on cable, and if iTunes is going to be releasing them I'd rather just buy it from them.

Any ideas on a time frame?

I'm pretty sure every show is in the store as soon as the show is over

I've looked. I don't see it. Maybe I'm not looking in the right areas?

They don't have all the seasons avilable.
