Apple prepares new products

Apple Insider has taken a peak at the outside of the building and notes that in addition to the typical iOS 8 and WWDC14 banners, there are also several others that are covered up. It’s pretty typical for Apple Inc. (NASDAQ:AAPL) to do this sort of thing. According to the website, the iOS 8 and WWDC14 banners are on the ground floor of the Moscone Center, where registration is already taking place. Apple is keeping anyone from going upstairs, however.

Those on site can see some banners that are covered up two levels higher. Apparently it’s possible to see the tops of some banners that are partially covered on the floors that are higher up. However, there’s still no telling what’s on the banners.

What may lurk behind Apple’s hidden banners?

Apple Inc. (NASDAQ:AAPL) CEO Tim Cook could tell us more about what’s on those banners in today’s keynote speech. There are a couple of interesting notes on Apple’s schedule for tomorrow at WWDC. At 9 a.m. Pacific on Tuesday, Apple has something listed as “No Comment” under Tools and another item listed as “This One Is Sealed” under Media. There’s also a third one titled “Shhhh, Can’t Tell You Yet” under Graphics and Games and a fourth one titled “It’s Under Wraps” under Core OS at the same time.

We’ve heard plenty of rumors leading up to WWDC already. Of course there are the usual things, like the unveiling of iOS 8 and all of its updates. Apple Inc. (NASDAQ:AAPL) is also expected to show off the next version of its Mac OS X 10.10. Some have said we’ll also see a new health monitoring app called Healthbook.  Other possibilities include more details on the Beats Electronics acquisition and Apple’s plans for home automation.
