Apple (AAPL) released its fiscal third-quarter earnings on Tuesday, and while last quarter the company sold 35.2 million iPhones -- a 13% increase year-over-year -- iPad sales sunk to 13.3 million units, a 9% decrease year-over-year.

Wall Street Journal reporters Joanna Stern and Doug MacMillan weighed in on the disconnect between iPhone and iPad sales.

“As we move into this post PC era and as Apple looks for its next legs of growth beyond the PC, it is looking like the iPhone is going to have to carry the brunt of that for Apple -- and perhaps other new products in the future,” MacMillan said. “iPad sales are declining and that device looks like it is not the future of Apple as some thought years ago.”

Stern thinks the alleged new “phablet” design of the iPhone 6 will compensate for poor iPad sales.

“I think that bigger screen [iPhone 6] that’s been rumored… will be the perfect blend for some people who are looking for the phone and tablet experience,” she said.

And despite rumors of a potential smartwatch or phablet, Stern says Apple’s concern is making sure the consumer just has an Apple device in their hands, whether it is an iPhone, iPad, MacBook, or iWatch.

“Tim Cook just wants us to have a screen that runs Apple software,” Stern said.

But can Apple again come up with a product that will change the world?

“Apple has this unique challenge that it is one of the biggest companies in the world and yet it has the highest expectations from investors. Those investors are looking for a breakthrough, revolutionary and disruptive product,” MacMillan said. “So far, in Tim Cook’s tenure, that has not happened yet….it is going to be very difficult for Apple to meet that expectation.”
