Yesterday marked the day that Mega Man 10 was released on WiiWare. The Playstation 3 and Xbox 360 versions will follow in the next days, both in North America and in Japan. It'll cost you 1000 Wii points, which are worth about 10$ USD.
The game information page on Nintendo's website reveals the upcoming downloadable content, including the identity of the third playable character: it's none other than Bass! A picture has also surfaced showing his new NES-style sprite alongside Treble.
