7 grand makes sense. Where there's a large fanbase, there's also fans (even if it is literally one or two) that are either fanatical enough or rich enough to go for it. If you think about it, VIP Axxess is kind of the same on a smaller scale. Here's a chance to meet your hero!... for $100 a head.
But yeah, I bet by "WWE Legend", they will give them Jim Duggan or some shit. And the top superstar thing is pretty much a game of roulette, if you land Cena then it should be a warm reception, if it's Punk or Orton... maybe notsomuch
