That would be a bad thing imho. Nikon's coolscans are among the best short of drum scanning. I'm thinking that the V competes directly with the 5000, but sells for half as much. I can certainly see them moving away from low ticket items, especially in the film-to-digital arena.
I agree, I have both...no wait, I have a IV and a 5000. At the time I bought the IV it made sense to have two tiers of 35mm scanning capability, now with the V priced equal or above equivalent flatbeds, there is no point for it. Five years ago flatbeds could scan prints...and that's pretty much it. I had a slide adapter for an expensive HP flatbed at that time...what a piece of crap!
I bought the 5000 because I realized how much of my life I was wasting without batch scan capability for slides...and it wasn't worth it.
