Many would want to get glimpses of Apple's iPhone 6, iPhone 5S and even the iPhone Mini via the WWDC 2013 scheduled next week but one analyst believes the world will have to wait a bit more.

RBC Capital Markets analyst Amit Daryanani is fairly convinced that the Apple event will not offer anything big, at least for those waiting to get previews of the tech giant's 2013 smartphone and tablet line up.

The general mood among Apple watchers and investors is tempered as far as the rumoured WWDC gadget unveiling is concerned, Mr Daryanani stressed, echoing too the earlier declaration made by Apple CEO Tim Cook that the company will only start showing off its big guns by September.

"Beyond WWDC we believe the focus remains on product innovation and we expect multiple product lines to be refreshed in 2H:13," the RBC analyst was reported by BGR News as saying in a new research note.

Set for unwrapping at around that time are two iOS smartphones, the iPhone 5S and the iPhone Mini, which Mr Daryanani said would be the first mobile devices to showcase the fresh look and capabilities of the Jony Ive-redesigned iOS 7.

Through these new handsets, Apple fanboys will savour the revised operating system's flatter icons, highlighting Mr Ive's efforts of moving away "from skewmorphism ... or digital interfaces that replicate the physical look," the analyst said.

As widely reported, the second half of 2013 will also mark the arrival of Retina on iPad Mini 2, doubling its screen resolution from the first rendition, and the major redesign of the iPad 5 that was purportedly patterned after the first Mini.

The fifth-gen iPad will sport a slimmer and lighter profile while displaying upgraded capabilities at the same time, Mr Daryanani said.

The rumoured phablet-size iPhone 6 will be crashing on first half of 2014 but Apple will still pull a giant surprise by unleashing a 'mystery' gadget, which most likely would be the iWatch or the iTV, the same report said.

For next week, consumers would surely get the new builds of the MacBook Pro and the MacBook Air plus significant OS bump ups with highlights on iCloud and Siri, the RBC Capital Markets report said.

The yearly WWDC will kick off June 10.
