Chinese analyst Sun Chang Xu believes Apple will launch two iPhone models with screens measuring 4.7 and 5.7 inches in June.
Also supporting a summer launch was a report by Chinese publication Tencent that claimed a 4.7-inch iPhone could go into production in May and another 5.7-inch model could be presented in the fall.
The larger model could get a higher screen resolution than previous iPhone generations.
The publication also wrote that the same 8 megapixel camera, with a new optical image stabilization technology and F1.8 lens, will equip the next Apple smartphone.
The Wall Street Journal reported this week that two new iPhone models with bigger displays could arrive later this year.
One such device would feature a 4.5-inch screen and for the second the display would measure more than 5 inches.
The new iPhones could be released in the second half of 2014, with the 4.5-inch model in preparation for mass production, WSJ wrote.
The report added that the two models will be built with metal outer cases, similar to the iPhone 5S and that the smartphones won’t feature curved displays.
An article by Forbes contributor Ewan Spence detailed the reasons why he believes a 4.9-inch display is likely to get implemented by Apple in the future iPhone.
Spence supports his ideas by explaining how the company released the iPad Mini with a 7.9-inch screen, while competitors launched 7-inch products.
He also expects the same 1136 x 630 resolution on the device.
A article by 9to5Mac argues that the current iPhone resolution could be doubled at 2272 x 1280 pixels in order to spare developers of having to update applications.
A leaked iPhone 6 case that was featured in a video this week turned out to be an iPhone 4S component, according to MacRumors Editor in chief Eric Slivka who shot down the rumors on Twitter.
Finally, Taiwan’s Apple Daily reported that the effectiveness of sapphire displays for the iPhone 6 has been undergoing assembly tests.
Foxconn has managed to successfully build an initial run of 100 iPhone prototypes with sapphire glass screens.
