Player Maruine of the Magtheridon server wanted to know if the pre-60 accelerated leveling mechanic was going in with the next patch (2.2).
Community Manager Drysc confirmed that it will NOT be in the next patch and he could not give confirmation of which patch it will go live. The only future patches we know of right now are 2.3 that introduces the new 10-man Zul'Aman and 2.4 with the Sunwell Plateau including its 25 man raid and 5 man instance.
Though many players are happy with reduction of experience for each level and the increase in experience gained from questing pre-60, some questioned the impact of this change on other aspects of the game.
Reputation gain was one concern. Since quests granting rep will go grey faster, will rep gains be buffed? (No.) Hunter pets were also brought up. There is already a problem with the Hunter outleveling their pets. Will this also be tuned? (No.) Lastly, will gold and loot drops be increased since some classes have much higher training costs then others? (Again, no.)
Drysc did say that if any of these factors become an issue, they will be addressed, but at this time, they don't have plans to do so.
