Very interesting. Formerly, The Guild posted their episodes on YouTube, which not only let browsers there find them easily, but let sites like this one embed and spread the word about the series. But while MSN has a video site, it's not immediately clear that they'll allow embedding -- it may not be so easy to spread around/watch episodes if The Guild is no longer uploading to YouTube and other video sharers. The Guild will have an embedded MSN player on their currently-being-redesigned site (complete with ads), but we're not sure whether we'll be able to embed it any more or not.
We will, however, find out the whole story on the new season (which will apparently include a holiday special) this week when we talk to Felicia Day herself on a special episode of our podcast, the WoW Insider Show. Look for that by next weekend, and keep an eye on the site on Tuesday -- even if we can't embed the new episode, we'll be sure to let you know where you can see it.
