I received the Haneke box set today. Just couldn't resist the great price!
The Blu-ray discs all come in sleeves that share the same design, having "Le cinéma de Michael Haneke" and the original film poster art on the front. It's actually quite nice.
On first look all films appear to have received recent HD transfers. Only the made-for-TV film Le château looks quite soft and could be based on a TV master.
What's probably of interest for most users here: For the most part the set is not English friendly.
I'll go through the set and the available audio/subtitle options film by film.
Le septième continent
German with forced French subtitles
Benny's video
German with forced French subtitles
71 fragments d'une chronologie du hasard

(Note: It's not possible to play the French dub with French subtitles)
Le château

La pianiste

Le temps du loup

Caché

(Note: The French subtitles are colored according to a special code and if no one is talking three dots '...' are permanently displayed)
Funny Games U.S.
English with forced French subtitles
French dub
(Note: It's not possible to play the French dub with French subtitles)
Le ruban blanc
German with forced French subtitles
French dub
French dub, including French narration for the visually impaired
Additionally all three audio tracks can be played with normal French subtitles or French hard-of-hearing subtitles
Amour
French
French, including French narration for the visually impaired
Additionally both tracks can be played with French hard-of-hearing subtitles
(Note: The French subtitles are colored according to a special code and if no one is talking three dots '...' are permanently displayed)
So in summary: Only three films are English friendly, namely Funny Games, Code inconnu and Le temps du loup. Additionally Funny Games U.S. is English friendly if you don't mind the forced subtitles or your player can remove them anyway. If you don't speak German and/or French you should probably avoid this set.
