I stopped in at my my local photographic purveyor today to inquire if he has heard anything as to the availability of the Ilford Postcard Paper. He wasn't even aware that it was making a comeback, so he made a phone call to the distributer. The individual there told him that it will be shipped from the UK within the next two weeks, and should be available for purchase sometime in the first week of March. It will be available in 100 count boxes, in either gloss or pearl.
Hopefully just in time to get started for the post-card exchange...
