Rift fansite Magelo have put up a soul tree calculator to test drive your awesome new build
Soul Tree calculator >>> http://rift.magelo.com/en/soultree/pts
A list of all the new abilities:
Cleric Support soul, the Oracle: http://rift.magelo.com/en/pts/abilities/60/Oracle
Mage Tanking soul, the Arbiter: http://rift.magelo.com/en/pts/abilities/58/Arbiter
Rogue Healing soul, the Physician: http://rift.magelo.com/en/pts/abilities/59/Physician
Warrior Healing soul, the Liberator: http://rift.magelo.com/en/pts/abilities/61/Liberator
Bare in mind, this is all based on PTS and is subject to changes and stuff, what you see now will not necessarily be what we end up with in 2.7
**Edit**
Added new links for abilities, apparently the old links were polling out of date data so a lot of the abilities were obsolete
