Im 90% sure this is entirely fake, as in, the DVD's and these cases do not physically exist, but the EwokAdv pictures were pasted over a real photo of some other movie collection. The original photo could have very easily been 'The Godfather' Box set with the Bonus CD and case 'photoshopped' out.
I could do the exact same thing and make a "Clone Wars" box set photo.
Fake or not, I'd love to see the set made.
