I think so. They also discontinued the LV mono PSP case which I wanted another one for a friend!
Oh so the PSP case is already out of production even if PSP is a lot newer than ipod mini?? :S
Try to take a look at LV website, I think I saw somewhere (UK or France) a white MC ipod mini holder, it was this year, maybe last summer
Maybe they have some left in your local store?
