I never have exact release dates, the factories give me shady estimates and the harbors are even worse.
You like the name? I changed it after I found out my boss came up with that silly retroGEN name and I could effectively name them whatever I wanted. He thought "retro genesis" would be cool and I felt that "retro generation" would be great for a sub brand but definitely not for individual products.
Either way, Sega has many of their products after planets. Earth and Pluto weren't taken yet so we snagged them up. Our next Sega product will be named Uranus...
