It seems that Werrason is holding Koffi Olomide responsible for Heritier's departure.

they mixed wata's letter and what werra said just after ingeta release 
werra has not talked yet and in his phone podcasts is almost doing as if nothing has happened

thinking about it  this situation reminds me of alain mpela's departure,which was also announced on tv through a letter written and read by alain himself and that similar context of the "second leader" of a band leaving and people wondering how the groups will cope with it
but i am sure guys like kedino miel de son must be drinking champagne like crazy now
there is gonna be some serious competition to claim that position wata had on stage next to nsone

Lets wish him well, I strongly believe this guy has done his research well and will start with a bang. To him he has everything he need and must make it big.

Of course it’s sad to see Heritier leave for has been with Werra for so many years. But Werra had major departures than this boy....talk of Ferre,Emelia,Adjani,Baby Ndombe,Mulopwe,Kapaya,Kabose,Serge Mabiala,Thiery Synthe,Celelo,Bill ,lacoste and so on and so forth. So i see sone pulling of off this one easily. His departure was long overdue but badly timed
