Seems like everything announced has been new colors or holograms.
I understand that's more profitable than new models, but only for so long.
That being said, they also may feel like they've run out of new ships to make that would be popular. Sure, I want the Fondor Haulcraft from Andor, the Onyx Cinder from Skeleton Crew, a YT-2400, the Caisson from Zero Conpany, the Star Tours Starspeeder, and a TIE Phantom; but I recognize those are not as grossly popular as more prequel and OT recolors.
MGS is not like Xwing the Miniatures Game, where niche ships could still be popular because of attached game mechanics and cards.
Ahsoka Season 2 looks to have one or two major space battles, but no new ships. The Ghost, Bwings, TIE Bombers. New opportunities for recolors, but no new models.
Unless MGS decides to take a risk on investing in niche ships from video games, Legends, and less-watched Disney+ shows, I am not sure we will see many new models.
