Back from the 80s: Jakob Hellman
Way more exciting than a potential ABBA reunion, but even still kinda underwhelming: renown recluse artist Jakob Hellman will once again grace the live stage on an 80s reunion tour under the banner "Forever Young" alongside Reeperbahn (and Alphaville): http://www.foreveryoung2010.se/
Still no plans for a new album and personally, I think it's better that way.
