I just upgraded an old style stick from to 128 gb yesterday and it worked fine. Format the SDXC card as Fat32.
FWIW, SanDisk Tech Support was clueless. "Doing this will corrupt the firmware on your Stick!", etc. Worked fine.
I have the original stick and a newer version (200gig) that I use, primarily, to keep my music collection on when traveling. Works well.
Other than the goofy USB slider on the original stick that sometimes gets in the way when connecting to some USB ports, they're really slick little devices.
