If you can afford to spend $1500 on the Pass, your experience will be completely different. Unfortunately the Pass creates two different experiences: that for the wealthy and for everyone else.
Yes, this is life unfortunately. The more money, the better treatment. There are a few points you made that I want to clarify too for people who are thinking about the $1500 pass...
First, the pass is MORE expensive (by $500/ticket) than it was in 2011 and you get LESS. Not getting exclusive session access might really put a damper on the $1500 you just spent (or $3000 for two people), especially if there is something you really wanted to see. The other benefits aren't really changed, which aren't the main reason to go to the Expo anyway. The MAIN reason people go is for the presentations/sessions.
Also, from what I'm understanding as a RUMOR, because they got rid of the Premier tickets for 2013 (a premium ticket in between normal and Sorcerer's available in 2011), they might be selling MORE $1500 tickets than last Expo. This means instead of ~50, there might be anywhere between ~100 to ~300. This might really put a damper on the exclusivity of the ticket itself which was to feel like you were in a small VIP group. Considering you are paying so much you want to be treated special, no?
Another thing to think about is airfare, hotel, food, and souvenirs (which you can't pass up at the Expo!) which are all NOT included in the price. If you are going to spend $2500+ on yourself, or $5000+ as a couple, you have to think.... maybe I could go to Hawaii for a week instead? Or split that money into two vacations?
And finally, the tickets go FAST. Like gone-in-10-seconds FAST tomorrow morning. There are countless Disney fans who are willing to pay ANY amount of money to get the best Disney experience, even if they live in a shack. So just because you can afford the tickets and want them doesn't mean that you are going to get them. With D23 events it's almost like the lottery... you are just going to have to get lucky to get the tickets. I personally know of at least 5 couples online (10 tickets) who have stated they are going to try for these tickets right off the bat.
Just some food for thought.
