Here in Australia they are still falling, although the fall has slowed a lot. The lenses still hold their value but the very common lenses such as the 80mm and 150mm are are bargain these days.
Still reckon that this is a great time to get into a V system because prices are still very reasonable, especially if you look at the older C cameras or the very cheap and often overlooked 500ELM. I can't imagine that prices will ever rise again because a lot of people think that film is dead
