A Disney VIP tour is not "skip the line". You wait in the LL line with everyone else, but you don't have to book times and you can reride things (other than ROTR) during the tour as many times as you want (remembering the price quoted above was based only on 7-8 hours; if you had an "express pass" like Universal's, you could use it open to close, so that price above that is currently charged for the VIP tour doesn't cover that many hours). Some guides do more "tour guide" things than others, talking about park history or pointing out things. Having been on several VIP tours in the past, the main reason that I think the vast majority of folks book them is for the almost unlimited LL access (you do get VIP seating for fireworks or WOC and/or Fantasmic and/or parade on the day of your tour). So yes, someday Disney might offer something like Universal's EP, but it will have to be much, much more than $100/person/day. If they offer it, I am sure there will be many who will take them up on it.
