i wrote an e-mail to FW to ask if they gonna update eldar stuff or just keeps pumping out imperial bullshit this is what they wrote:
Thank you for your email. We are currently looking at what errata is required for our books due to the release of new codex's and the latest edition of the 40k rules. Once this is completed, we will release any required updates on PDF, via the downloads on our website. As this is a massive under taking it will take quite some time to complete.
If there is anything further we can do to assist you, or if you have any queries about the information we have requested or provided, please telephone us.
hope they realy update our stuff and not the ridiculli imperial rules
