This is certainly good news. By the way, both are listed as 2-disc sets. 

La Roue 

"This new restoration with a running time of nearly four and a half hours, accompanied by Robert Israel's symphonic score, is the fullest presentation of La Roue to reach the public since 1923. It at last allows audiences today to experience the amazing, poetic vision that Abel Gance brought to the world. The DVD also includes a short film that provides a vivid documentary record of the great work in production, along with a booklet containing an outstanding essay by William M. Drew on the history and impact of La Roue, and comments by Robert Israel on the score." 

J'Accuse 

"Lobster Films Studios, Paris, working in collaboration with Netherlands Filmmuseum have culled materials from the Lobster Collection, the Czech archive in Prague, the Cinematheque Francaise, and the Netherlands Filmmuseum to make the best possible and most complete edition of the original 1919 edit of the film."
