Smashing Pumpkins Change Band Again

The Smashing Pumpkins are amidst another line up change.  According to Blabbermouth.net, Billy Corgan has given the boot to Rage Against the Machine drummer Brad Wilk and Killers bassist Mark Stoermer.  Stoermer had just joined last fall.  He's replaced by Katie Cole.  Former Chris Cornell and Courtney Love collaborator Robin Diaz is assuming drum duties.

No reason given for the changes, but with "emotional" Billy Corgan, is one really needed?
