The EI, Zodiacal, is set to evolve on the friday closest to the next Zodiac sign. It came out on the 19th of January when first introduced. The sign of Aquarius begins on January 20th. Therefore, it was purposely introduced on January 19th, because it is the Friday closest to January 20th.
Because the next Zodicac sign, Pisces, begins on February 19th, I'm almost positive it is set to evolve today, since it's the closest friday to the 19th.
Below is a picture of the dates of the certain zodiac signs. You may use this to also make your own predictions. If you notice a pattern between evolutions and real dates, and it's different than my present accusation, then send me a message.
