The question is then, would a detail-less product, with a divided attempt at high and wood versions, 6-8 new careers, 1-2 pages on epic/high magic, ", with token mention of the Druchii, and no map for either Ulthuan, Athel Loren and the Great Forests of Empire, be better than no product at all? I'm of the camp, that we'd get a weak product that would be empty on useful details and padded with a couple sheets of cardstock counters. Not to short FFG for their business and design decisions, but I'm not hopeful that anything is being produced, much less than it would be a stellar work of GM and player useful bit of gaming literature. (I"m wrong..I can just feel it in my bones. How's that for a schitzo' attitude on the subject?)
In the meantime, you have the 2e Fan supplement on Wood Elves (excellent) and Yepsnopes Careers put forth for the High Elves (well done), and the near-useless fantasy battles books (meh…)
A proper WFRP3 elf product would be a large boxed set that would be LOADED with juicy, tidbit-laden fluff, by authors who are BOTH experts in the subject matter (FIRST..and needed!), but also able to translate that into useful material.
