Bandai Namco has been quite active lately . The company has filed some interesting western trademarks in the last few days. ‘Lost Song‘ was trademarked in the United States and Europe, as well as ‘Eyes of Heaven‘ and ‘Lost Reavers‘ in Europe.

‘Lost Song’ is the subtitle to the upcoming ‘Sword Art Online: Lost Song’ for PS3 and PS Vita, which was only confirmed for a Japanese release, so a western release seems quite obvious.

Eyes of Heaven‘ is, again, another subtitle. JoJo’s Bizarre Adventure: Eyes of Heaven for PlayStation 4 and PlayStation 3 was initially announced for Japan.

Finally, Lost Reavers was also trademarked in Europe and the States, but we still don’t know what it might be pointing to.

Stay tuned.
