Cathay Photo also sells XQD cards. I got the 64GB G series, off the top of my head can't remember how much exactly, but around $20ish less than Sony's RRP. They didn't have the Lexar XQD cards, only Sony. That was like 2 weeks ago.

Agree with the compression point and that's why I'm starting to go with the 70-200 f4 for portraits. It is sharp, the VR is phenomenal, and the compression works together with the depth of field to make the subject pop out from the background.
