It's kind of a mixed bag! - some French DVDs include full subs (i.e. not just French subs for the hard of hearing) and some don't. I'm really not sure what the criteria is for including them or not. :/ I'm really hoping the film gets distributed in the UK, at least, and then we won't have to worry about it so much because a R2 UK DVD would surely have them.
(Wait, is this your first introduction to Jamie speaking French? Oh, do go back and look through old posts on the comm. His actual French accent is MUCH better. ;) )
