This is according to his spokespeople and Ndombolinho Leader, I haven't really heard the reasons but  Heritier instead will be releasing a coupe decalle generique instead on that day. 

I think we all saw that coming....I watched the embarrassing excuse his spokesman gave...they said the workers who work in the cd duplication factory are on holiday and therefore they can't release the album lol...come on

Haha, I caught that too. Nonsense. I mean, it's a perfect time at the moment since there won't be any other releases for sometime.

Congolese and due dates gotta love it.

yes unless they gave it to factories too late in august he may be right,it takes between 2 and 3 weeks in general unless its a period where there is not too much demand
notice nowaydays most album either are released in the first half of year or in late june then from october to new year
but they must admit there is another reason and i have my idea on it lol

The reason I have in mind is that, he's waiting for the others to release first so that they don't steal his spotlight if they release after him.

yeah also possible especially with his "beef" with fally both are playing mindgames,heritier's release looks closer but i am sure he tries to check,lets not forget that fally and ferre's albums are much awaited and it could cause problems to all those guys with a recent solo career and bring back focus on fally vs ferre

If Heritier is confident in his work and he his sorcerers are guaranteeing him success then heritier should not be scared to release before anyone, Fally and Ferre haven't really talked about their new albums a lot while Heritier has and plus people know what Fally and Ferre bring so they might want to here what heritier has to offer first.
