The Titans of Ether used to run the Ultima 9: Redemption and Ultima: The New King projects for many years. In December 2016, Ultima 9: Redemption was cancelled, and the Titans embarked upon a new project called Corven - Path of Redemption, which isn't Ultima-related. They have since rebranded to Lycantic.
Ultima - The New King originally aimed at producing a sequel to Ultima 9: Ascension. After officially merging with the Redemption team on 18th September 2004, it is, instead, going to be a sequel to Redemption.
The website for Ultima 5 for Morrowind went live in February 2005. The site doesn't seem to exist, but I haven't checked whether the project still exists elsewhere.
Redemption began under the lead of Avatus. Problems arose when he left; the team lost motivation and the project was heading for a fall. In September 2004, however, Corv from Ultima - The New King offered to join forces, and the two teams merged to form the Titans of Ether.
After 12 years in development, the Titans of Ether also gave up on Ultima 9: Redemption and cancelled the project in December 2016.
The soundtrack [Spotify | YouTube] for Ultima 9: Redemption, composed in 2006-2008 by Matti Paalanen while the project was in the hands of the Titans of Ether, has survived.
