Hmm, it does sound interesting, but it is too early to judge what it will be like seeing as it was just revealed today. But i do agree it looks like a great episode!
Although, i also hope they don't overhype it as well. ( By the way, the release date for this DVD that this episode will be on is March 16th. They said it on the site that was mentioned. Sorry, just felt like saying that).
The plot of it is interesting though.
