The Just Dance 3 facebook page just said in a very recent post ''We're in the works of Just Dance 4. What do you want to see?'' , I'm not sure if this is an Ubisoft run page ( though this would fall in line with other rumors and general expectations), but it's worth a mention. On a side note , what music would you like to see in JD4 and would it be better on wii or wii-u?
