Jim Dalrymple says:
Very reliable sources familiar with the product have said speculation of the tablet being introduced during the September event are flat out wrong. The Apple tablet, they said, would not see the light of day until the first part of 2010.
The event in September will be focused on music, which means we could see new iPods and perhaps some updates to iTunes. The tablet computer will not even be mentioned as part of the event, my sources said.
While in response to Brian's account on the conversation with someone claiming to be in the know, Gruber has this to say:
I'm almost certain there's no tablet coming this year. It's a 2010 thing.
Both seem adamant about it. Unlike the usual rumour sites—who are a random hit-or-miss most of the time—Gruber has an almost perfect track record when it comes to breaking news about upcoming Apple products, usually right before an event.
Still, the truth is that very little is known about Apple's super-secret new products outside of a handful in the Cupertino campus. And while that handful may spill at some point, the information is usually vague until very close to the release date. In other words: While the sources pointing to a 2009 Apple tablet release may be wrong, Gruber and Dalrymple may be wrong too.
Heck, for all we know, everyone may be wrong, and this whole tablet thing may end being just a wet dream. Or maybe everyone is partly right, and there will be a September announcement and the tablet will be available sometime in 2010, similarly to what happened with the iPhone. That will give iPhone app developers time to prepare their software for the new format.
