So i watched the entire section of the dimension and here's what Trion has said...
- They know we want more item limits but can't promise anything.
- Fishing items will be BOA in 2.2 patch.
- Reclaimer's Gazebo dimension item is a hoax and not even in the game. No need to fish for it anymore
- More NPC dimension items are coming but not many due to difficulty. Something about it being harder to code than objects.
- They didn't answer my question about the Specimen Display whether that item is a hoax too.
