The association's members are well known for sure. If more new devices and cameras making use of XQD aren't released in 2012, expect card prices to remain high until volume uptake forces down manufacturing and distribution costs.
Hopefully, the buss speed of the slot 2 CF interface accommodates the newer high-speed/high capacity CF cards.
