Will CD+DVD versions make clip collection DVD obsolete?

[M_aria]

Since Avex (is any other label doing this?) does CD+DVD versions of almost every release, do you think they will stop doing PV DVDs? Ayu hasn't had a DVD release since Complete Clips Box, hitomi's last DVD was Frozen in Time, Namie had Filmography 2001-2005 which is okay considering that there really hasn't been too many PVs out so far, so I suppose you can exclude her, and I think Kumi Koda only had that "Spirits.." DVD (but I haven't really followed her DVD releases). And those are just the artists I pay attention to... I'm sure there are a lot of other popular artists with the same thing going on.
