Is Bertelsmann music sale upcoming?

Rumour has it that Bertelsmann have hired JP Morgan and CitiGroup to prepare for a sale. No word on what they are selling but, as previously reported, the consensus is that their music publishing business and their stake in SonyBMG are most likely to go. As also previously reported, Bertelsmann are considering the sale to raise enough money to buy out shareholder Groupe Bruxelles Lambert who are pushing for the media conglomerate to float.
