New Foucault Book?

This is listed as forthcoming on fnac.com

Michel Foucault, Philosophie  [essai (poche)], Gallimard Folio Essais, 15
septembre 2004

>From this, and the low price of 7 euros i assume it is probably a reprint of
material, i guess from Dits et ecrits. Foucault's book on Raymond Roussel is
in this series, whereas most of the other cheaper editions of his works are
in the Tel series. But anyone know any details?
