Namco Bandai trademark filings hint at unannounced mobile Katamari game
Three other trademarks found

According to Siliconera, Namco Bandai has filed a trademark in Japan for 'Katamari Damacy Mobile Jumbo' – a possible future mobile entry in the Katamari series.
Various trademarks containing the word 'roll' have also been filed, including 'Roll City', 'Roll Period', 'Roll World', and the conceivably related 'Around the World'.
Furthermore, 'Katamari Amore Rolling Whopper' has been filed in Europe and the US.
Previous mobile Katamari title Rolling with Katamari fared well at Pocket Gamer, earning a Silver Award at review.
Away from the Katamari series, Namco Bandai has filed a further three trademarks for 'Blood Vengeance', 'Dark Escape', and 'American Life'.
