Breaking with recent tradition, Apple will reportedly not be holding a media event in October of this year, with the company said to be planning to lay all of its cards on the table — including the anticipated "iPad Pro" — with today's media presentation in San Francisco.

Citing "lots of little birdies," John Gruber of Daring Fireball indicated on Wednesday that Apple is not expected to hold an October event this year. In recent years, Apple has held announcements about new iPads and Macs for the month of October, spreading its product unveilings out over two presentations.

Conventional wisdom would have suggested that products such as a rumored "iPad Pro," as well as a 21.5-inch iMac with 4K Retina display, would have been held for an October event.

But from what Gruber has been told, it's expected that a new 12.9-inch iPad will be unveiled at today's presentation, with no October event in the works.

That would make today's "Hey Siri" event particularly jam packed: Apple is also expected to unveil the "iPhone 6s" and a larger "Plus" variant, as well as an all-new Apple TV with App Store. It's also likely that the company will showcase the main features of its soon-to-launch iOS 9 mobile operating system, and may also dedicate stage time to its forthcoming Mac update, OS X 10.11 El Capitan, as well as the Apple Watch update watchOS 2.

Gruber had predicted on Tuesday that he didn't expect new iPads to be unveiled at today's event. Instead, he assumed that the company would hold off on any iPad news until its usual October event, as it has done since 2012.

But with Wednesday's update, the author admitted he was "pretty sure" that his earlier prediction was inaccurate.

"So if there's an iPad Pro, it's coming tomorrow, no matter how much or how little that makes sense," he wrote.
