I can tell you about Frost
Jem Godfrey recently posted on his website that he is free from a record label. He is trying to see if he would release a couple of songs digitally and then next year release the album through the normal channels. There is supposedly a live album coming from Frost later on...Don't know if Ken is going to stock it though...
I'm not sure about Kino. Haven't heard anything from Pete through the Marillion website. Right now he's going to be busy with Transatlantic and the recording of Marillion's next album since they are in the studio right now. Personally, I would a Kino album as well...
I don't know anything about Arena though
