Karaoke Equipment & Supplies

Does anyone know if the Wii version of Karaoke Revolution American Idol Encore will have downloadable songs?

I know the game currently does not feature this but has anyone heard whether there are plans in the works to have down loadable songs, like they have for the PS3 version?

I highly doubt it. AT this point, the only music games on the Wii even RUMORED to have DLC are
Megaman 9
Samba De Amigo (only rumored)
Guitar Hero 4

Rock Revolution Trailer – PS3, 360, Wii, DS
