Besides a 4.7-inch model, Apple has been expected to announce an even larger 5.5-inch iPhone 6 this fall. But now production issues might keep Apple from pulling the trigger on an iPhablet until winter or even 2015.

Ming-Chi Kuo of the Taiwanese firm KGI Securities, who has been a consistently reliable source of information on Apple’s plans, isn’t bullish on seeing a 5.5-inch iPhone by the end of the year. Problems with the phone’s new display and casing could result in it being pushed back until well after the 4.7-inch iPhone 6 comes out.

As we patiently wait for Tim Cook to kick off Apple’s WWDC keynote in just under five hours time, the last of the WWDC rumors and reports are spilling in. One of the more questionable pieces comes from KGI analyst Ming-Chi Kuo, who believes the new MacBook Pro won’t get that thinner, lighter, MacBook Air-like form factor we’ve all been hearing about. But that a resurrected MacBook will instead.
