Respec news for the New Frontiers expansion is up on the Camelot Herald. Below is an excerpt from the detailed write-up, to read more just follow this link:

With 1.70, we’ve made so many great changes to the game. As a result, there will be some free respecs given, so that you can tweak your character just the way you want it. Here’s how it’s going to go: Realm Ability Respec: - The first time you log in, whether that’s launch day or a year from now, you’ll find all your realm ability points stripped and back in your pool. - Assign your points as you wish. - For one week after we launch New Frontiers (the date is still not set, by the way), we will be selling special, temporary realm ability respec “stones” for ten silver pieces. You can buy as many of these special and temporary stones as you like, and experiment your heart out. But be warned! After one week, the special stones will disappear. So hold on to any normal respec stones – there will still be a market for them after the first week of New Frontiers is over.
