For arguments sake, I'll use Lucky Bancho's recent census. I will also assume out the 1.1M active characters, only a quarter of them are individual players. At $24 each, this amounts to $26.4M reasons why SE changes what they do. If cutting that in half, it's still a staggering amount of money. And that's for only four mounts.
Another thing to consider is Sleipnir has been out much longer than the rest. Still though that's a ton of cash.
