There has always been an upgrade for iPhones, from iPhone 5S to iPhone 5C and now the upcoming iPhone 6. As for the comparison with other brand's devices and the history of iPhone, there is an immense pressure on what the next generation would become.
Rumors all over the Internet spreads faster and we cannot tell if some are real or not. Most of these rumors focus on the screen size of the device which is expected to increase from 3.5 inches to 4 inches or more. Apple has been expanding with a variety of experiments for the iPhone 6, like discussing the forming of the screens from a super-hard "Sapphire Glass", and is expected to compete with Samsung Galaxy S5, Sony Xperia Z2 and some frontliner androids.
Apple is expected to release the iPhone 6 (which is said to be 4.7inches) somewhere in September this year. Launching this device might also be delayed for a short time due to the disagreements about the launch date and production issues which has to be resolved sooner or later.
Surveys in the U.S shows that consumers named the iPhone 6 as the "most anticipated Apple Smartphone ever" compared to the previous iPhones. These consumers most likely expect the iPhone 6 to be a major revision of the iPhone including the entire design. Also, this will likely cost around a thousand dollars or so.
Rumor or not, this iPhone 6 might receive mostly positive reviews, where iPhone has been receiving for almost a decade ago. Or maybe a bit of a negative - but these rumors can be verified for real once Apple finally releases the next-generation, iPhone 6.
