One idea that occured to me as I read this thread was the possibility of talking with other fans of anime in France who are tuned into the pulse of the country more and talking with them or checkingbout their websites, blogs, etc. They might know more about the kind of details you are wondering about.
There are some active members from France in tne forums here as well, so if they see this thread maybe they will be able to point you in places you coukd begin to look too....
Best of luck to you.
