Is Apple Moving to Plastic Chassis with iPhone 5S and iPhone 6?

Each time Apple talks about the launch of a new product, there is much speculation and rumour regarding its specifications and design. Although no official date has been announced for the release of iPhone 5S and iPhone 6, rumours have already kicked in.
Designer Ran Avni, an Apple enthusiast has taken out a video to show us what the anticipated iPhone 6 might look like. Considered a low-budget phone, iPhone 5S will be seen sporting a plastic casing and will be targeted for lower-income groups. However, the concept video by Avni shows that Apple iPhone 6 will also be seen in a similar plastic casing.
As shown in the video, the iPhone 6 will come in both black and white colour just like all Apple smartphones. With a design similar to the iPhone 5, the only visible difference seems to be the plastic chassis.
Apparently, the iPhone 6 is shown with a physical Home button. There is a lock screen and speaker bar at the bottom with a headphone jack beside it.
However, as video contains still pictures, there is no image of how iPhone 6 might look when in action. As for the release date, it’s known that the Cupertino calif.- based company won’t be releasing both the devices together. There will be a gap of at least six months between both the releases.
Anticipated to release anytime soon, the iPhone 5S might attract consumers with better specifications and low budget. The iPhone 6 is thought to be released next summer.
