One of my mole told me SS11 is likely to see the light and that casting will open in March or April, but since the talking between the production and the channel are being in a good progression it could even open this month.
Well..., I think SS11 if there is, will be the last season. (in the TF1 group at least). And then, probably NRJ12 or some channel will take it in a few years. (Now, three months after SS10, I see clear, and I can say that SS10 was disappointing, disgusting, the cast was good but mixed up it's just not possible).
