Even though the introduction of the iPad-only publicationThe Daily is slated to also herald the coming of iTunes app subscriptions early next year, don’t necessarily expect that move to suddenly make your iPad a digital stand-in for the local newsstand: traditional magazine publishers remain skeptical of Cupertino’s app subscription plan because of the company’s refusal to share credit and billing information.

Whenever it arrives, it looks like Rupert Murdoch’s The Daily won’t be the only iPad-only magazine around: British billionaire and part Virgin Airways owner Richard Branson is also planning on launching a new iPad publication called Project, and it’s likely to be revealed as early as tomorrow.

The past week’s rumor cycle has consistently pegged early December as the date when Apple would simultaneously introduce iOS 4.3, iTunes in-app subscription support and News Corp’s new iPad-only magazine, The Daily… but according to sources, that date is very likely aggressive, and the actual rollout has been delayed until early 2011.

iOS 4.2.1 was just released, but already the rumor mill is churning about iOS 4.3… and it looks like it might arrive before the end of the year, much earlier than anyone had previously thought.

According to sources, Apple plans on releasing iOS 4.3 on Monday, December 13th… just three weeks after the debut of iOS 4.2.1.

Following yesterday’s story that Steve Jobs and Rupert Murdoch might meet on stage to debut the world’s first iPad-only newspaper, comes a new report suggesting not only that Apple will hold that event on December 9th, but also use it as an opportunity to unveil a new subscription billing option for periodicals on the iPad.

Both Rupert Murdoch and Steve Jobs agree: devices like the iPad are the future of media, and the death of print.

It looks, however, like Apple and News Corp. might be working more closely to bring that end about than it was previously thought: according to WWD, Apple is helping News Corp. build an iPad-only, subscription-based newspaper to devices in early 2011… and Steve Jobs himself might debut it.
