Remember how Nintendo didn't show anything from Smash Bros. Brawl on the first two days of E3 2006, but gave the game a surprise showing to close off the third day? This is exactly like that, except with Onechanbara R instead of Smash Bros.
Onechanbara R is the latest entry in D3's hack and slash action series that started as a Simple 2000 budget game on the PlayStation 2. The series, which subsequently appeared on the Xbox 360, is mostly known for its heroine, who wears a bikini and cowboy hat. In fact, to announce the game during the first public day of E3 today, D3 brought out gravure star Erina to cosplay the character (see famitsu for the results).
D3 is making the game Wii-ready with a new control scheme that puts the Wiimote to full use. You use the nunchuck analogue stick to move around, and press C to ready your sword. To swing, you hold down B on the Wiimote and swing away.
This latest in D3's attempt to take its Simple series out of the gaming ghetto and into full-priced releases is being prepped for a Japanese Wii release in 2008.
