I can easily see Blizzard get greedy if it takes off though, aggressively pushing new items for players to keep the edge, like fucking seasonal arena gear for real currency.
This is exactly what will happen. It's just D3, so it's not going to be a big deal. But this is going to become a huge balance issue in future games if Blizzard pursues this system with all their games. Particularly with their new MMO on the horizon. It's an obvious ploy to snuff out gold farmers, but it's a double-sided sword.
