A new Aquarion TV anime has just been announced, called
Genesis of Aquarion: Myth of Emotions (or Aquarion MOE for short
)
Anime News Network
More details will be revealed at the AnimeJapan event on the 25th - 26th of the month.
The new mecha looks to be a modified version of the original Solar Aquarion, so hoping this'll be more in line with say the original series or EVOL, rather than Logos.
