I've just found out about this very recent French edition of Montaigne's Essays:
Michel de Montaigne, Les Essais, edited by E. Naya, D. Reguig-Naya, and A. Tarrête. Paris: Gallimard, 2009. Collection "Folio classique," 3 volumes, 2182 pages, € 21,10. This new edition is based on the Exemplaire de Bordeaux.
