ABC News' Sarah Parnass and Jennifer Wlach report:
Between Donald Trump's "big announcement" and the ongoing "October Surprise," there is intrigue on the Internet in this last leg of the presidential election.
Trump's surprise started last week, with a cliffhanger of a tweet Friday afternoon: Donald J. Trump ?wrote, "I'll be making a major announcement on President Obama next week - stay tuned!"
Then, after a weekend of silence on the subject, Trump offered a few more details about this 'major announcement' during his weekly phone interview with Fox & Friends. "It's going to be announced probably on Wednesday. But I have something very, very big concerning the President of the United States," Trump said Monday morning on the show.
When the Fox & Friends hosts inquired whether the announcement was of a personal or professional nature, the business mogul said it was both, adding, "It's all in one, everything. It's very big. Bigger than anybody would know."
Since this morning's teaser of an interview, callers have flooded Trump's offices for additional information, but nothing more has been revealed. Not even Trump's active Twitter feed has hinted at more. When asked about the announcement and what to expect, Michael Cohen, Executive Vice President and Special Counsel to Trump, would only say, "Unfortunately, I am not at liberty to disclose the nature of Mr. Trump's Wednesday announcement. Without question it will be big."
Inquiring minds will have a distraction tonight while they wait for Wednesday - Trump will be live tweeting during tonight's third and final Presidential debate.
Before the debate starts, another Internet secret is set to be revealed.
The site drew in users with the promise of secret documents that might change the Romney/Obama race in the way the Iran-hostage crisis transformed the Carter-Reagan election of 1980. ( Read more about that October surprise here.) A countdown clock that took most of the site's one page was set to reach zero at 6:30 p.m. ET today.
With that, it seemed all loose ends were tied up. There were no documents, just a harmless prank on the journalists and netizens too obsessed with the election to see past the farce.
But as of this morning, the countdown clock has started up once again, and even OctSurprise itself doesn't seem to quite know why, tweeting , "Who am I? Why am I here?"
With any luck, the world will know soon.
