Smashing Pumpkins frontman Billy Corgan spoke to Kerrang stating that the Smashing Pumpkins will never become a "Nostalgia Act".  The band is gearing up to release a new album called 'Oceania' in 2012.  He also said that they will never succumb to pressure to do a tour around just classic material. The Smashing Pumpkins currently have remastered their first two albums Gish and Siamese Dream and are available as deluxe editions, but the band will continue to make new music.

When asked about the demise of the Smashing Pumpkins Corgan responded as he didnt want the band to end just to depart a few members.

I never wanted to leave the Smashing Pumpkins in the first place. I wanted to leave some of the people, but not the band. I tried a bunch of different projects and they were interesting, but they weren't satisfying. The Pumpkins is only thing I've ever found in music that gives me the passion I need. When I wasn't doing it, I didn't really know what I was doing.

The band is wrapping up a UK Tour and is planning to do a European Tour in 2012 with perhaps some dates in North America.

One other thing to note Siamese Dream celebrates its 20th anniversary in 2013.
