For those of you in the US without Cartoon Network you should know that new episodes this season will premiere on Adult Swim Video the very next day. Not sure what time they'll put the episodes online, but look for them on Monday. Note that this is different from last season when episodes premiered online the Friday before they were shown on TV, so adjust your calendars.
You can also download this much larger one if you like.
Edit (1:18am EST): Sorry, forgot to mention my source on this. Thanks to io9 for posting a couple new shots (though most have already appeared on Jackson's blog).
Right now there aren't any episode names connected to the production numbers beyond the first two episodes, so it can get kind of confusing. The numbers refer to production order, but everything here is listed in airing order.
If you want to skip around, James and Jackson come on around the 1hr 19 minute mark.
Patrick Warburton is signed on for this season, some back story including who or what Dr. Orpheus was married to, and some focus on the villain Monstroso.If you do decide to read the rest of the article note that it contains spoilers pertaining to Handsome Ransom, so if you want to be surprised you might want to skip reading it. Suffice to say it sounds pretty good.
