It's not an official statement, but after sent a mail to Daserste, i received this reply today
"From September on, Thore Schölermann will have a break of four months from "Verbotene Liebe" to concentrate on other projects.".

This means, that we will not see him from approximately December till March 2013 in VL. ( due to the 3 months of decalage beween the filming and broadcasting )

Chris is finally with his husband in an hotel room. So, this mean, yes Olli is back :)

This is the third video Liebe ist... with just the part of Chris and Olli :)
