The 5.5 to be more powerful

While both new models are expected to be upgrades of the current set, Wang says that there maybe a big difference between the 4.7-inch model and the 5.5-inch model.

"I believe that we should watch for the differences between the 4.7 model and the 5.5 model," said Wang. "The differences in the models won't just end at screen sizes.

Wang expects the 5.5-inch model will be a bigger upgrade than the 4.7-inch model. She says that the 5.5 may come with better hardware compared to its smaller brother. She implies that the 5.5-inch model may be even more powerful than the 4.7-inch version.

Apple to release the new phones with China being one of the first countries to see a release

Last year, Apple released the iPhone 5c and 5s were released in China during the first wave. This was the first time that China included among the list of countries to receive the iPhone first. Previously Chinese Apple fans had to wait longer periods of time before the device could be purchased on the Chinese mainland. Wang says, this year, China will mostly likely still be part of the first countries to receive the new device.

"China has become an important market for Apple and the iPhone will probably release in China the same time it hits the United States," said Wang. "This year, it'll be problem free, with the LTE issue being solved."

Last year, despite China being a launch country, Apple released an LTE free version of the iPhone first in the country. LTE is a mobile broadband technology that allows for faster downloads and Internet surfing.

However, Wang does warn that there maybe differences in release dates for the bigger 5.5-inch iPhone and the possible wearable device. She expects the base 4.7-inch "iPhone 6" will launch first at the same price point as the iPhone 5s. She says the 5.5-inch and the wearable will probably come some time later.
