You're right, the current product range only includes Lumion, Lumion Pro (and Lumion Free).
Lumion Ultimate was part of the product range of Lumion 1 and 2 but will no longer be updated once Lumion 3 is released.
In other words, Lumion Ultimate license-holders will have to upgrade to Lumion Pro 3 if they want to continue to receive updates.
