All the SD cards I've seen have FAT filesystems on them.  The firmware in cameras almost certainly can't handle anything other than FAT.  Android devices with SD slots probably expect FAT SD cards too, though they might be able to handle ext3.

FAT actually makes sense for removable storage in many situations, because everything can understand it and UIDs/GIDs don't make sense for things that can be attached to different devices.  I don't think it'll be possible to get rid of FAT for this reason.  (And isn't there something called ExFAT that SD-using devices that take cards > 32G are required to support?)
