"tuscan 81 along with a few other models won’t be available in this run. Nor will sound locos (sound now unlikely to happen). Full details in the pre-order confirmation letter that is starting to make its way into peoples hands.

There might be several schemes which are delayed but this still doesn't explain why the NR versions aren't on the BL Order Form.
