Kind of bummed about PK doing the Eldar codex. As much as people say that the DE and Eldar book have aged well, I disagree. The DE lists I see are getting homogenous and the Eldar book is just riddled with worthless units like Swooping hawks and shining spears and points costs that even at the time didn't make sense. The thing about Ward's codexes is that there are often several different viable units in it and combinations that are fun to play. I know that my BA codex has so many different builds that are fun to play with and at the same time won't get you ROFLStomped on the table.
The only silver lining to the Eldar codex not being released until 2014 is that I will continue to enjoy the gnashing of teeth as I watch my friends roll 12+ on 3D6 for their psychic tests for at least another year and a half, maybe two at this point, who knows.
