Remember folks this may well be only the tip of the iceberg. I remember when Amon Amarth released "Cry of the Black Birds" ahead of the release of their latest album. Most people were impressed, but still many skeptical. When the album With Oden on Our Side was at last released, people were all blown away as most of the tracks on the album were much better than the one released ahead of the album.
Keep the faith, DT still may have a surprise in store for us.
