New Samba De Amigo trailer, no sign of maracas

The new Samba De Amigo trailer is out, complete with a break dancing chimp!
But what is interesting, no actual maracas addon, just a standard Wiimote, and nunchuk setup, not a rattle anywhere...well apart from the chimp, which pretty much goes to confirm that there will be no official addons from sega, i'm guessing we're going to have to go unofficial as reported earlier this week.
