There has not really been much on the High Elf rumor front, but really we are only a few short weeks from seeing the pre-releases for the army. So leaks should be appearing anytime from this mid-week to early next week.
There are a couple small tidbits from warseer though that have popped up, and here they are.
If you missed the last compilation update... here is the link.
