well, looks like instead of episode 4 of OVA3, we're getting a special, which is titled "Tenchi Muyo!: Himitsu Nabe (Entertainment)" (Quick translation of Himitsu Nabe: Secret Saucepan - I like the ring of it
)
Anyway, it's coming out on May 28th, and it looks like it' sgonna have all the OVA characters as well as GXP characters. The DVD cover has a circle of characters on it, starting from the 12:00 position and going clockwise, there's Amane, Aeka, Washu, Ryo-Ohki, Fuku, Mihoshi, Ryouko Balta, Sasami (Holding... something... Maybe a nabe?), Ryouko, and Kiriko.
I dunno, I'm looking forward to ep 4 since the plot's finally moving along at a good speed, but this will probably prove to be highly entertaining. I love it when Tenchi (Or anime in general) doesn't take itself too seriously
