Currently there's quite a bit of buzz on the mailing lists I'm on about my current read - The Girl with the Dragon Tattoo by Stieg Larsson. By all accounts so far, it could be a rival for Vargas for the International Dagger.
I've put a couple of lists together on amazon for new Scandinavian crime novels coming out in 2008. One is for amazon.com and one for amazon.co.uk. They are slightly different due to books coming out earlier in one country than another.
New Scandinavian Crime/Mystery Novels (amazon.com)
Forthcoming Scandinavian Crime Novels (amazon.co.uk)
