Just a short while ago, Pokémon Sunday teased silhouettes of the starters from Pokémon Black & White. Vigilant as ever, fansite Pokébeach managed to get the scoop on a high-res image. The complete artwork will be revealed in the upcoming issue of CoroCoro magazine, which is expected to leak sometime this week.
Until then…the one on the left looks the most likely to be the grass starter. I’d say fire in the middle and water to the right.
