Wade Robson is breaking his silence on the Michael Jackson sex abuse allegations ... and it sounds like he's about to drop a bombshell.
Robson surfaced at JFK this morning -- unsuccessfully trying to stay low-key in a hooded sweatshirt and sunglasses.
But when the paps recognized Robson, they immediately blasted the guy with questions about his accusation -- that MJ molested him when he was a kid.
TMZ broke the story ... Robson claims MJ was a monster who sexually abused him for years ... but he didn't take action sooner because he repressed the memories. The MJ estate says Robson's allegations are completely bogus.
Robson says he'll open up about the situation tomorrow.
Stay tuned ...
