SEGA may be releasing a new console

I've been recently playing the PS3 game Hyperdimension Neptunia which is focused on four goddesses who rule over four different lands. There's Black Heart, Noire who rules over Lastation, Green Heart, Vert who rules over Leanbox, White Heart, Blanc who rules over Lowee and finally, the player character Purple heart, Neptune, who rules over Planeptune.

The game is made by five companies: Nippon Ichi Software, Gust, Idea Factory, Compile Heart and SEGA. Along with the four goddesses, there are four characters. Compa, IF, Gust and Nisa.

In case you couldn't work it out, the goddesses represent game consoles and the characters represent game companies. The companies are Nisa - Nippon Ichi Software, Gust - Gust, IF - Idea Factory and Compa - Compile Heart whereas the consoles are Black Heart (Lastation) - Playstation 3, Green Heart (Leanbox) - Xbox 360 and White Heart (Lowee) - Wii. But if you count, there's no character personifying SEGA, and there's an extra goddess who doesn't represent a console. This is where my theory that SEGA plan to release a new console comes from.

Now, I do realise that the name "Neptune" is a reference to the SEGA Saturn but why is she purple?

All of SEGA's consoles have been black, except for the Dreamcast which was white. Now, I realise that Neptune couldn't be the Black Heart because that's taken by the Playstation 3 but wouldn't it have made sense to make Neptune the either the Blue Heart or Red Heart in this case? The reason I say Red Heart is because if you look at the SEGA Master System and the Mega Drive (Genesis to you Americans) you'll see that there is red on them. Blue Heart is simply because their logo is blue and their mascot is blue.

Of course, I could just be reading in to it too much but if SEGA do release a new console, just know that I was the first to call it.
