I think we are looking at a saturated market. Lots of new stuff coming out, and maybe people have a little less to spend on extraneous items right now. Personally doesn't affect me, as I won't even look at high end items. I'm a strictly low-end buyer, and I buy what I like, not for investment. 90 percent of the sketch cards in my collection are PSCs, purchased because I liked the art, and could afford the cards. My idea of high end is purchasing 3 packs of Viceroy Cards releases.
