Well apparently this thing has been known for quite some time before today, though in case you missed it…

Phantasy Star Eternal Hunters and Phantasy Star Eternal Planets were trademarked in August. This leaves us to believe this could be a new game, or a game feature, or maybe nothing will come of it.
You can view a screenshot of the trademark at Shougai's site.

Both works are categorized under trademark categories 9 and 41. Category 9 trademarks fall under video game storage media including: CD ROM / Game Cartridge / Laser Disc / handheld game / computer game / etc… Category 41 falls under animation / play / drama / etc…
Because it falls under soo many different forms of storage media in which a video game uses, we can assume it is a video game.

Additional Comments
The only thing I could tie to this title is that the Hunters were from PSZero. That's all I can say for now. Its just best to not think much of this for now.
