Coffret Intégrale des 24 aventures: the ultimate edition?

Digging around for information, I came across mention of a Casterman boxed-set released last year. It contains all 24 Hergé Tintin books in eight volumes, and seems to include some documentary material, but excludes the non-Hergé trio of movie books.

Has anyone seen this, and does it appear to be definitive? I'm just wondering if all the books have had their artwork retooled, as they did for the restoration of Black Island.
