Pokemon Rainbow to be announced tomorrow? - Report

While Nintendo has already announced that its first Nintendo Direct for 2013 will feature Pokemon news, exactly what this announcement will entail is anyone's guess.

However, an anonymous source cited by Go Nintendo believes that the publisher will use tomorrow's live-stream to announce a new Pokemon 3DS title called Pokemon Rainbow.

"The game encompasses the settings and Pokemon from generations 1-4: Red and Blue, Gold and Silver, Ruby and Sapphire, and Diamond and Pearl," the source told Go Nintendo.

"You can take my word for it that the graphics are done up very nicely. The perspective is similar to what you'd expect from Pokemon games, but the camera is much more dynamic. The graphical style is characterised by very clean, dark lines. Battles look radically different and move away from the use of pixel art."

According to the source, the new game is concurrent with Pokemon Black 2 and Pokemon White 2's storyline and features over 20 new Pokemon, two of which will reportedly be revealed tomorrow.

"One is an evolution of an older Pokemon Eevee, called Draconeon. The other is a totally new Pokemon called Verbill. It looks like a rodent, much like the Pokemon Patrat, but has a sort of pirate theme going on."

In addition, the source reported that a Wii U app will be unveiled tomorrow alongside the game.

The most recent core Pokemon games were Pokemon Black and White 2, which released in North America in October 2012 behind positive critical plaudits.

Both games cracked the NPD Group's top 10 United States sales chart during their debut month, but neither charted in November (a month filled with heavyweights like Call of Duty: Black Ops II and Halo 4).

The Nintendo Direct live stream will take place at 6am EST.
