I am referring to the SDHC and SDXC specifications, not the filesystem specifications.
Nintendo so far as adhered to the SDHC standard, and with the switch will embrace the SDXC standard.

If it wants to claim SDXC support then it must support formatting to exfat. It can claim to support SD cards up to 2tb with a proprietary format, it just won't be able to claim SDXC support.
As long as is not encrypted. I hate not being able to naturally backup save data or anything. 
I don't care what it is, just let me backup data please!

I can't imagine them using Fat32 or a custom partitioning.
Fat32 is not recommended for anything greater than 32GB.
Custom partitioning is just stupid and rarely used by any company for good reason.

id be smart if they used a custom format. Prevents a simple file copy unless the proper encryption keys are used. The wii U one is not even hacked yet as i recall, or its not public at least.
They could use an encrypted UFS......

ExFAT is not a requirement for SDXC. The 32 GB limitation on FAT32 filesystems is not accurate. It is an understandable misunderstanding as Microsoft Windows' partition manager will not allow you to great a FAT32 partition greater than 32 GB, but that's a Microsoft limitation. I've got a 200GB micro SDXC card that I popped into my Linux machine and reformatted to FAT32 with gparted.
The disadvantage is you cannot have files greater than 4GiB. It doesn't make sense to have such a large card and be unable to store large HD/4k video on it.
But yea you're right, You could format up to 16TiB as fat32.

for the SDXC specification and the use of the SDXC logo, it is a requirement. FAT32 will work on a card larger than 32GB but it will no longer be SDXC compliant.
if the Switch is SDXC compliant, it will use exFAT for cards larger than 32GB and FAT32 for cards smaller than or equal to 32GB. my guess is that smaller cards 2GB and below will not be formatted as FAT12 or FAT16 as per the SD standard but as FAT32.

And the disadvantage of ExFAT is that it's a proprietary Microsoft format while FAT32 is ubiquitous and used by everything.
I also can't see them sticking to FAT32 due to games being larger than 4GB having issues, unless the system somehow splits the games into 4GB chunks. That I could see working.
Splitting them into multiple files should not be a problem. I mean, look at USB loading on the Wii for example; if you used a FAT32 filesystem and a game greater than that 4GB limit, it would be split into multiple files.
FAT32 originated from Microsoft.
I never said anything about exFAT.
You need to stop assuming things.
I said I doubt they would use FAT32 or a custom partitioning.
They could use many better/more open partition types. Fat32 is Microsoft in the same way exFat is.
It couldn't be custom. Custom wouldn't be compatible with vWii, which was the point of having SD at all.
I never said you said anything about ExFAT. However, as the default file system (and while we're being pedantic, 'file system' and 'partition' are not interchangeable terms) on SDXC cards, it is the next logical choice for a file system after FAT32 or a proprietary Nintendo file system.
As for FAT32 being Microsoft, not quite. They did indeed work on it, and they do have a patent relating to it, specifically with their implementation of long file names. But that can be and has been worked around. FAT32 is the ubiquitous file system that is supported by pretty much any device.
There are software you can grab on multiple os to allow formatting beyond 32GB. However the maximum file size still applies.

Microsoft cares cause they can then charging for licensing.
