FAT32 is not very practical system for sizes over 32GB. Even Windows 
refuses to format partitions over 32GB with FAT32. I guess FAT table is 
too large to be efficiently handled by memory restricted devices.

See table and explanation here

I wonder if they will agree on some different filesystem for bigger 
cards or try to stretch FAT32 beyond 32GB.
