yea cant really test its full compatibility without either getting a game over 32gb (none exist or ever will as far as i know) or multiple roms totaling over 32gb on the card..
id assume if they say sdhc only in their support emails its probably exactly like the dstwo limitation then.. dstwo...
actually sdhc and sdxc has more to it than just the formatting it comes with... sdxc card formatted with fat32 will read fine in sdhc readers but anything beyond the first 27gb will not be addressable.. i ran into that limitation with my dstwo.. i was able to access all the roms i copied over to...
