Schedule of release of items for donation for Frostmourne

Hey,

So I'm wondering whats the schedule for item release for donations in Frostmourne as well as prices?

1. Are the prices gonna be the same as the prices of things on Icecrown?
2. Are things going to release for donation when some % of people have them? I need to know how long it will take for things like PvE offset or certain weapons to be released for donation as a lot of them have a use in PvP too and it would influence my itemization decisions.

Thanks
