The band, who release their ninth studio album later this year after releasing single tracks online as part of their 'Teargarden Of Kaleidoscope', said the success of the album will shape their future together.
Speaking to Billboard, Corgan said: ''If we're able to get that sense that something is happening again and get people to rally behind us a bit, I think the next three, four years will be very interesting for the band. I think if ['Oceania'] basically hits the same wall a lot of the other stuff has hit, we're going to have to step back and really evaluate where we're going, because it's a tremendous amount of energy to put out to just feel like you're throwing a pebble in the ocean."
Smashing Pumpkins have announced details of a UK tour, which is due to take place in November.
The tour also includes two gigs at London's Brixton Academy on November 15 and 16, and will conclude at the O2 Academy in Birmingham on November 19.
