We have two possibilities here..
 
A) Both Harmonix and Green Day "put there money where their goddamn mouth is", and make this the world's M-rated rock band game
or..
B) We get a neutered Green Day expierience. 
Having your own video game isn't very rock and roll in the first place, and censoring your music to push some extra units is straight up blasphemy for the genre. 
 
Words such as"Methamphetamine" , "masturbation", "cocaine", "niggers", and "Mary Jane" are used in their biggest hits.. How would do you guys feel about being instucted to use these words in your video game?

lol, Green Day.

" lol, Green Day. "

fine by me, but MTV most likely wont allow it, theres only been a few RB songs that have swearing in them intact ("Uncle John's Band" By the Grateful Dead).  I really dont think they will change that now. 
 
 
also, this

I don't know what everyone has against Greenday, I like a lot of their stuff.  
 
On topic; obviously I'd prefer them to make it M rated so we can actually listen to the songs, but I don't see it happening. I won't get my hopes up.

yeah... not gonna happen... it's gonna be T...
No way would they make it uncensored when the official Rock Band game is still rated T, with edited DLC being released...

There is no way in hell that this will be rated M. Sorry, it'll be censored.

They said goddamn in El Schorcho

It will get the rating of "FD". 
For "Fucking Disgrace". 
Also, potentially "S" for "Sucks".

People really hate Green Day don't they? 
If they censor this one up too,then screw this.
