I saw that earlier in the week myself. It leaves a lot of questions unanswered, though, like what version(s) of CE it'll support. I'm guessing 6.0 or higher, since ExFAT has some similar features to NTFS that FAT32 didn't have.
Haven't gotten any response from Tuxera to my e-mail yet. Maybe I'll contact the Paragon folks and see what they say. Meanwhile, I'll be posting a news item on this as soon as we lowly mods regain access to the staff console.
