Billy Corgan is reportedly working on a plan to get the original line-up back together for a tour and, in a video he has posted on his Facebook page, he teased: "there's some big stuff happening".
Billy added: "We're making plans. I can't give that away, but it's going to be interesting."
Billy, drummer Jimmy Chamberlin, guitarist James Iha and bassist D'Arcy Wretzky have not all performed together in over 16 years.
And an "industry source" told Consequence of Sound that he is trying to put together a Smashing Pumpkins reunion for a series of gigs and festival slots in 2017.
Original bass player D'Arcy previously admitted she is keen to rejoin the band after she was fired for "being a mean spirited drug addict who refused to get help".
And Billy admitted he is "encouraged" that the rocker is making music again and seems to have left the door open for her to return.
While wishing 'D'Arcy a Happy Birthday, the singer wrote on the band's official Facebook page: "Speaking of those I've been fortunate enough to share the stage with, I see that it's D'arcy Wretzky's birthday today: So a big and happy B-Day to her from here! I'm encouraged to hear that she is playing music once more, and writing songs. As I've often said, no one had better musical discernment in our band than she. (sic)"
Billy reunited with Smashing Pumpkins co-founder and guitarist James for their 'In Plainsong' tour in April, the first time had performed together in 16 years.
After the run of dates which concluded in Ft. Lauderdale in May, Billy expressed his desire to continue Smashing Pumpkins as he signed off the message saying "see you next tour".
His post stated: "As I head home, it's crazy to think that it was nearly 30 years ago that I began this wild and wooly journey, and that meeting James [Iha], then D'arcy, then Jimmy [Chamberlin] would alter all of our lives forever; for the better, I would argue. Which I suppose makes the hardships that came too, bittersweet.
"And as I feel speculation start to swirl about what happens next for SP, I'd like to say quite simply and directly that what matters most to Jeff and I is the music. Because from our darkest days together over the last 10 years it's been our faith that the music we make, and by extension our loving curation of the songs made from the beginning on, that'd sail this old, creaky ship forward to another year. So see you next tour, wherever and whenever that may be! WPC (sic)".
