KGI Securities analyst Ming-Chi Kuo has, in the latest Apple-related speculations, said that the bigwig tech company will introduce some substantial changes to its next iPhone lineup in 2017.

Speculating that the iPhone lineup in 2017 will unfold completely revamped iPhone models, Kuo said that the company will likely revert back to its recognizable glass casing for the new iPhone lineup, and will also apparently launch a model with a 5.8-inch AMOLED display.

According to Kuo’s projections, Apple will go back to the glass casing for the 2017 iPhone models, similar to the iPhone 4 and 4s models. Kuo is of the opinion that though a plastic casing or a ceramic casing could possibly be mulled by Apple for its 2017 iPhone lineup, the company will eventually decide on its familiar glass casing for the handsets.

Kuo has specifically projected that the 2017 iPhone lineup will likely feature a curved frame, a curved screen, a glass front and back, and metal sides. Despite the fact that the projected design of the next-year iPhone models appear to be a reminiscent of the iPhone 4 yet again, Kuo has asserted that the 2017 iPhones will boast a "completely new" form factor.

Furthermore, in predicting that the 2017 iPhone lineup will come with a 5.8-inch model with AMOLED display, Kuo said: "If the supply of AMOLED panel is sufficient, we believe it is more likely that the first scenario will happen, in which case a 5.8-inch AMOLED model will entirely replace the 5.5-inch TFT-LCD iPhone."
