Square-Enix registers trademark for Cosmos Rings, possible follow up to the Chaos Rings series
One mobile RPG to rule them all

As spotted by Gematsu, Square Enix just registered Cosmos Rings in Europe under the classes for video games. A website was also registered today and could indicate that Square wants to launch a new game in the Chaos Rings series but that it won't simply be Chaos Rings IV.

The Chaos Rings series has been a landmark for RPGs built with mobile in mind and has been around for a long time. Sadly, due to some incompatibility issues with newer OSes, Square has removed some of its legacy titles including Chaos Rings.
This could also be a push in the premium market that Square Enix wants to focus on.
We'll let you know if anything comes out of this.
