You really chose the worst time to ask this question. The free PDFs for all the wave 2 stuff were literally taken down less than a week ago because of the release of the Wave 2 book and Arsenal decks at gencon in about a week.
I would PM CrouchingMoose or myself (or many others on the forum that have volunteered in other threads) for a copy of the PDF files, and as for the Wave 2 book and Arsenal decks, they will definitely be available at your FLGS some time in the next several months. We have been told that all the models being sold at gencon will be in stores between October and January, I have a feeling the Wave 2 book and Arsenal decks will not take that long after gencon is over to make their way into your FLGS.
