Bandai Namco trademarked "Katamari Damacy Encore" in Japan, further fueling speculation that there is a possible remaster of Katamari Damacy in the works. This follows reports that a trademark for "Katamari Damacy Reroll" was filed by Bandai Namco in Europe.
According to Twitter user @pierscesword (via Gematsu) Bandai Namco Japan registered a trademark for "Katamari Damacy Encore." Last week it was reported that Bandai Namco filed a trademark for "Katamari Damacy Reroll" which is a different title, but offers the same connotations. Presumably for localization differences.
The words "Encore" and "Reroll" hint that these trademarks could be referring to a Damacy remaster rather than a sequel. But it's only based on the context of these words and not any official announcement.
Katamari Damacy is a 2004 PlayStation 2 game where the Prince, on the orders of his father the King of All Cosmos, must travel to Earth and roll a giant ball that picks up other objects. It's a game about love if you can believe it.
Katamari Damacy kicked off the Katamari series with sequels coming out for the PSP, Xbox 360, PlayStation 3, Vita, and smartphones. Creator Keita Takahashi is currently working on the indie game, Wattam, with Annapurna Games.
