Inferno Metal festival, Oslo, Norway - 13th-15th April.
Wave Gotik Treffen, Leipzig, Germany - 2nd-5th June.
Wacken Open Air, Wacken, Germany - 3rd-5th August. (In Extremo and Subway to Sally already confirmed!)
M'era Luna, Hildesheim, Germany - 12th-13th August.
I don't currently have dates for Castly Party in Poland, although it is usually around the last weekend in July...
So who is intersted in going where? I think I'll be at Wacken and M'era Luna again, and travelling in Germany in between like I did this year. I also have friends who haven't been to either that have expressed a strong interest in going to these festivals. Not sure about the others. I mentioned the Norwegian festival as it is one country that I've always wanted to visit and the festival also takes place at Easter, but I'll probably wait for the line up before I decide further.
