Knowing MTV, they probably will.
I don't expect the awards to air over here any time soon. Last year's Japanese awards or something were aired on MTV2 a few months back, but cut into (if I remember right) a 30 minute show with only the Western performances and only a few snippets of Japanese, during presentations (
as well as a really lame effort from Joel of Good Charlotte to speak Japanese 
). Hopefully they won't do that to this Aid thing.. I might tune in, even though I really, really loathe MTV and the Western performers featured..

At least it's for a good cause.
