Like most MMO's, they're going to release the actual life day event a week before Christmas. So it will most likely come out next week. Think of these items as "special" life day items. There will probably be a completely seperate adaptable set of armor with the event.
No an BW poster has flat said in another thread there will be no life day event.
I posted the link to it earlier in this tread if you care to look for it.
