If the info above is to be believed, then that means no new ponies for at least two more weeks.
So that just means you’ve got more time to pick apart the mythological framework of the first two episodes, or make more fanart of Fluttershy tied up on the ground.
[UPDATE] Some guy (goes by turtwig. I stole this, shamelessly) with a better cable service got to see another week out. The next episode airs on the 15th. Also EqD apparently has hookups with the people who do TV listings and the description of the new episode is out as well:
“Hyper-organized Twilight panics when she can’t find a lesson about friendship for her weekly letter to Princess Celestia.”
Sounds like a good time to me! -plaster
