No because I believe that Omega isn't the Final Boss of the Raid series. The way it is being presented is that the Omega is the first section Interdimensional Rift.

Patch 4.0 will have Interdimensional Rift - Omega, 4.2 Will likely have Interdimensional Rift - Shinryu.

We didn't call A1 through A4, G1 to G4.
