Wildcards for Melodifestivalen?

Rumours have been circulating regarding who the 4 possible wildcards for Melodifestivalen could be!

One that looks certain is Sibel who placed 7th in Melodifestivalen 2008 with 'That is where I'll go' which reached number 6 in the Swedish charts.

Peter Joback's name has also been mentioned as a possible wildcard. Joback is regarded by many as being one of Sweden's best male vocalists.
A star of the musicals Peter competed in Melodifestivalen 1990(complete with 90's hair!) performing 'En Sensation' finishing 9th. Check it out here

E.M.D. consisting of Erik Segerstedt, Mattias Andréasson and Danny Saucedo all met while participants of Idol 2007.
Their first album 'A State of Mind' debuted at number 1 in the Swedish charts. Danny was rumoured to be approached by Christer last year but was unable to accept the invitation as he had already signed up to be a contestant on Let's Dance 2008.

Ace of Base the band that have scored 12 UK top 40 hits and 4 time winners of 'Best Selling Scandinavian Artist' at the World Music Awards have been mentioned many times as possible entrants over the years.
Last year Ulf Ekberg of Ace Of Base told Expressen 'We have definately not closed the door, if we only can get it in so it works with our world tour. It a very interesting platform'

Who else could be a contender? Nanne? Caracola? Marie Picasso? Afro Dite? Kikki? LaGaylia Frazier? Darin? Sebastian? Magnus Carlsson? Jan Johnason? Melody Club? Man Meadow? Bionido? Thorleifs?
The mind boggles!
