I don't think the VDZ is going to die off anytime soon because of the improvements made from the original, and I do see a lot of people using one around here. The original was also popular back in the day, and if the Vintage is kept clean I think it could last you for quite a few years as well.
I also think, that, all of the balls you listed (and then some), except for the Soul, are going to be around for quite a while.
