We finally have titles and descriptions. for the new episodes. I'm in the process of posting them at the guide currently, but they can all be seen here.
Note that the descriptions there give away a bit more than I do in the guide --- one reason being that descriptions aren't supposed to be copied directly. You may also find the descriptions from that link to be slightly more spoilerish, so if you want to know just more basic detail to whet your appetite, I recommend reading here at the guide. But if you don't mind reading more detailed descriptions, then be sure to check out that link.
(If you're a member of the Yahoo Arthur group, you may have already seen that.)
