If the prices stay like that at release I can see the prices of items dropping drastically. Gear wise nobody would spend the 10k on a random boe item when they can get a heroic one (assuming people wont bid it up like crazy) and all the mounts will be a huge gold sink. Every server has a handful of mega wealthy players with nothing to spend gold on. This will probably help Blizzard move some of that gold out of their hands and hopefully stabilize the market a bit so a couple of users wont control everything. That's assuming people actually buy the mounts.
