Last month ChangeWave polled more than 4,000 people, who were asked if they would be willing purchase the next iPhone, a.k.a iPhone 6. The findings show that there is already high interest for Apple’s next generation smartphone, which is expected to debut in fall 2014. 14 percent respondents said that they are very likely to purchase it, while 26 percent responded they were somewhat likely.

This 40 percent together shows that there is significant buying interest than there was for Apple’s previous iPhones. ChangeWave conducted a similar poll in March 2013 when rumors about two iPhones being launched were circulating wildly. Back then only 26 percent respondents said they were likely to pick up the new iPhone, despite the fact that even at that time there were rumors about larger displays.

But the rumors seem to make sense now, given the fact that Apple decided to stick with the same size for yet another generation of iPhones. Many Wall Street analysts are now of the view that if Apple doesn’t want iPhone sales to fall flat it is going to have to adopt larger displays. This is presumably why people are now more likely to believe that iPhone 6 is going to follow current market trends, which evidently lean towards large displays.

ChangeWave’s parent company, 451 Research, said that “speculation over a larger screen iPhone is clearly striking a chord with consumers,” and that it is the highest level of demand for an unannounced iPhone ChangeWave has ever seen in its survey.
