Haha, this paragraph cracks me up:
Un accord entre Disney et Fox aurait été trouvé. Avec le rachat du second par le premier juste avant Noël, on imagine bien que les négociations - difficiles jusqu’à présent - entre les deux parties se sont vu énormément facilitées.
TRANSLATION: An agreement between Disney and Fox might have been found. Now that the former has purchased the latter just before Christmas, we can imagine that the previously difficult negotiations between the two parties has been enormously facilitated.
