Well with the new pets out there's no way KI can top this,

KI released this a while ago
The new world of Celestia is inspired by Atlantis, and young Wizards will encounter new adventures and quests deep under the sea. Celestia also increases the level cap in Wizard101 from level 50 up to level 60, as well as introducing three new secondary schools of magic. Celestia will officially open in late summer. Starting in June players can undertake new quests to discover the secrets of this new world and begin to unlock the story behind Celestia.
Unless I'm horribly wrong June is next month, Tomorrow, The day after today, but we'll see in the Ravenwood Newsletter if I am right. (this link won't work until the newsletters out)
