Efectivamente Hook, yo me decidí por comprar sólo el SACD de Wish You Were Here tras leer un comentario de Amazon UK, en el que al margen de los problemas que tu señalas se dice lo siguiente:

There is no question that Wish You Were Here is a 5 star album, but this Immersion box set is over priced and a disappointment.

Firstly, at the time of writing, it costs the same as the Dark Side Of The Moon Immersion box, £84.99, but contains one less disc. At least the Dark Side box contained an extra CD of demos and alternate mixes, which made it a little more desirable.

Discs 1 & 2, the remastered original album and bonus tracks, can be bought for £12.93 as part of the Experience edition.
For your extra £70+, you get 2 DVDs and a Blu Ray disc, replicating the DVD contents. Therefore, if you have a Blu Ray player, the DVDs are redundant. There is no doubt, however, that this is where the holy grail is contained, with the release of the long awaited 5.1 mix of the album, in addition to the original 1975 Quadrophonic mix and concert screen films.

As with the Dark Side set, the rest of the box is filled with 'collectibles', most rather pointless and of 'cheap' quality. The two photo books are flimsy and lack much content, the scarf and marbles are pointless, & the print, collector's cards, replica ticket and backstage pass are interesting to look at once, but you won't need to return to them again. EMI could have left all these out and cut the price.

If you have an SACD player, I would recommend buying the SACD instead, which contains the 2011 remaster and 5.1 mix. Although it has to be imported, it is available from European online sites for around £30, including shipping. That way, you can still own the 5.1 mix and save yourself £50 odd quid.
Teniendo en cuenta que soy solo un fan "moderado" de la banda, que ya tengo el DVDA no oficial con la mezcla 5.1 y que le doy más valor a las notas que tu escribiste en el 2007 que a toda la parafernalia iconográfica, pues con el SACD más que bien. Y ahora encima leo tu comentario. Pues está claro!!!

Un saludo
