OK mad bad. I misread the early reports of 256GB being needed for the Air, and hence understood it to be the case for the iPad Pro too. - Thinking that anything less than the 256GB would cane the SSD and cause premature wear as there is less space to lose the tired wear blocks over. (which is still a consideration actually if you think you're going to using apps that extend to 16GB regularly). But I agree, reading the footnote Apple has posted on the link above, there is no minimum specified for the IPPs.
