While there have been a number of Katamari Damacy games over the years, the frequency tends to be fairly lopsided, with the last non-mobile game releasing on Vita nearly eight years ago. On the gaming forum ResetEra, a poster discovered that Bandai Namco had recently trademarked the name "Katamari Damacy Reroll" for Europe. This was then followed up by a Japanese trademark for "Katamari Damacy Encore," hinting at a Greatest Hits or collection game.
While creator Keita Takahashi has been working on Wattam for Annapurna Interactive, he remarked earlier this year that he has been taking a look at his old games for "secret reasons."
i just needed to take a look at my old games for secret reason, and that reminds me old/good memories of course.

Additionally, some sources we have talked to have mentioned to Game Informer that Bandai Namco is making a big push with external partners for the franchise in the near future, possibly to coincide with a new game. With Tokyo Games Show, ahem, rolling in fairly soon, that seems like it could be a reasonable place to announce something.
Hopefully all our dreams are not crushed.
