Let's be fair here. The price could have been $300 and there would be "like" those same "30 people with their Sleipnir mounts."
There are some people that will pay the high price to get their content first. TPTB will have had made their money, before they conveniently give into community demand, and lower the price for some special sale event. Then they'll make even more money.
Now, charging money for content that wasn't even 100 gil, in game, last year? Yeah, that's totally pointless. Me thinks they're just experimenting with that one (to see how many people are that willing to part with their money).
