Latest words from analysts are stating the obvious - that the iPhone 6 following its release date will easily dethrone the iPhone 5S as the bestselling Apple smartphone ever.

Fresh from her checks with supply chain sources, Katy Huberty of Morgan Stanley boldly predicted that the iPhone 6 could prove to be the biggest product launch that Apple will undertake, likely overtaking the sales posted by the 5S since its debut in late 2013.

Early this year, Apple CEO Tim Cook described the iPhone 5S, its core features highlighted by the entry of Touch ID fingerprint sensor and 64-bit processing chip into mobile computing, as the highest selling iPhone model in Apple's history.

That could soon change, if Huberty's report is to be believed. The analyst pointed to the next iPhone, rumoured to be recipient of a major redesign inside and out, as the next giant revenue generator for the company.

Huberty forecasts some 20 per cent spike in overall iPhones sales this 2014 thanks mostly to the next generation of the device that according to reports will come in two builds - the 4.7-inch model and the first iPhone phablet at 5.5-inch.

According to Huberty, the iPhone 6 will shoot its way to the top immediately after its issuance and bump off the iPhone 5S. And here are the four reasons why the next iPhone is destined as the new consumer magnet from Apple:

Sufficient supplies on release date

The Morgan Stanley report also indicated that production of the iPhone 6 appears to have resolved all the manufacturing challenges that were mentioned in previous reports. Huberty, according to Apple Insider, "sees no major bottleneck for iPhone 6 components, suggesting that Apple and its suppliers may not have a difficult time keeping up with demand."

That means the anticipated millions of upgraders from the iPhone 5S and older models can readily access the new device, which for Apple will translate into record-breaking results that could extend into the early quarters of 2015.

Finally an Apple phablet

Also, becoming jumbo-size will play well for Apple's iPhone 6 as Huberty noted that by sporting alone a bigger display from the 4-inch 5S, the company is heading to sales growth path.

While Apple has yet to confirm of the impending intro for the supersized iPhone, a Canalys report points to an emerging smartphone trajectory that the research firm the company can no longer ignore - mobile phones with stretched display panels.

"Consumers now expect high-end devices to have large displays, and Apple's absence in this market will clearly not last long," BGR reported the Canalys report as saying.

NFC and mobile payment

Another lure for mobile device shoppers that Apple will pack with the iPhone 6 is near-field communication (NFC) capability that according to MacRumors will vastly improve the tech giant's in-place mobile payment facility.

"Apple is likely to incorporate a Near Field Communication (NFC) payment function in the next generation iPhone and has reached an agreement with China UnionPay on a mobile payment service," said the MacRumors report.

The same technology is also slated to play a key a role in upcoming Apple Store improvements, added the report.

Waterproof iPhone 6

Lastly, it is likely that the iPhone 5S successor will have an outer shell that can repel water and other elements, a Phone Arena report claimed, pointing to the images tweeted by known Apple gadget-leaker Sonny Dickson.

With the feature, the iPhone will match the IP67 certification that Samsung had earlier boasted about when it outed the Galaxy S5. However, a waterproof iPhone 6 is far from being confirmed as Phone Arena conceded that the images of an iPhone soaked in water, despite Dickson's solid reputation, should be taken with a grain of salt.

Release date for the iOS 8-powered iPhone 6 this 2014 is thought to be in two instalments - first for the 4.7-inch edition that could get unwrapped in August then for the hulking 5.5-inch build that would break the scene in September.
