Kizune, I belive the D2+ makes use of 128gb SDXC cards and not microSDXC cards. As far as I know, 128gb microSDXC cards isn't in production yet (probably held back until enough 64gb microSDXC cards has been sold..).
Thanks for giving out this info quokka, I suppose the 3.0 specifications is used for all
current SDXC and microSDXC cards then but I'm not sure if this will be the case in the future. Thanks for reporting back though
