Google is pushing forward with its thrust of delivering high-end but affordable Nexus smartphone to global consumers despite growing perception that the tech giant is simply opting to lend the Nexus brand to flagship devices.

Google Edition Galaxy S4, HTC One and Sony Xperia Z are coming out soon but according to Android chief Sundar Pichai, the basic plan remains in place and Google will upgrade its LG-assembled Nexus 4.

"The goal with Nexus was to push forward hardware with partners," Mr Pichai was reported by Gotta Be Mobile as saying, which explains Google's recent decision of adopting popular mobile phone brands to become part of the Nexus family.

Amidst these collaborations, the company, however, will stick with its Nexus smartphone upgrade cycle and here are three confirmed information about its 2013 Nexus 5 launch date.

Nexus 5 will rollout on Q4 2013

Google released the Nexus 4 November last year and consistency dictates this could be the same target date for its replacement. Or the tech giant could opt to advance the Nexus 5 debut by picking October as the unveiling time.

The timing jibes with the final gadget onslaught to occur this year, by which time the world would have seen the iPhone 5S from Apple, the Nokia Lumia 925 and Galaxy Note 3 from Samsung. Heading into the lucrative holiday quarter, Google would want to slug it out with the best of them and this time around it is ready not to repeat the mistakes that prevented the Nexus 4 from taking off big time.

Key Lime Pie will arrive first via the Nexus 5

Android 5.0 skipped Google's I/O Developers Conference in May but Android watchers that it will arrive this year, with October as the latest ETA. It could be that in a few weeks time, Jelly Bean 4.3 will be dispatched on Google's update channels but the major Android makeover will take place via KLP.

It is possible that Nexus 5 will be the sole KLP handset in the planet a few weeks after its release as it will take some time for other devices to accommodate the new mobile OS, the Nexus-flavoured HTC One, GS4 and Xperia Z including.

Also, Google will likely reserve the honour of displaying KLP first to the Nexus 5 and not to the Moto X, the Motorola 2013 flagship that is being developed with large amounts of Google technologies.

Still powerful and affordable

The look, the components inside the phone and the maker all remain a Nexus mystery. Rumours point to LG as the manufacturer while others assume that the Moto X will simply become the Nexus 5, solely on the account that Google now owns Motorola Mobility.

Nothing is definite at the moment but experts believe the upgrades will be obvious - faster processor at quad-core speed, better screen display with 1080p resolution, insanely great camera features, wider connectivity options, faster internet access and more exciting functionalities that will match up with the new possibilities created by KLP.
