I went with the iMac 27" 3.5GHz w/2TB. Ships to store. Available Nov 2 at Apple Domain. Seems unlikely there is a 2TB Fusion Drive shortage. Although the 1TB and 3TB Fusion are still in stock. If memory serves me correctly, new Apple hardware availability come quicker to the stores than mobile devices, as the demand is not nearly as high. What are the chances that hardware announced on 10/30 will be available that Friday, 11/2 as Friday's are always the order day for new Apple product.
