I think that this may not work out for many of us, i mean choosing backers randomly, 100 each month, who will have a choice between those three options and delivery of an Sony X image is about two weeks from now. From my point of view it would ve better that backers can already check in, i.e. decide between refund to be used for the Sony X image or donation. If i am chosen in about one year i would probably decide to get refunded, today i would prefer the Sony X image and on Christmas i might donate the refund:-)
