Buyable faster advancement coming to a MMORPG near you!

Warhammer Online started selling the Specialized Training Pack for $9.99, an item which makes all of your WAR characters advance one full level. Meanwhile EVE Online is offering the EVE Online: Commissioned Officer Edition as a new boxed set, which allows you to create a new account with a new character which gains skills significantly faster for the first 30 days (beyond the usual newbie bonus). As players have shown that they are very much interested in faster advancement, companies react by selling that faster advancement to them. Where will that lead?
