LG, after all, is considered a Nexus expert having its hand in the manufacture of two beloved native Android-toting gadgets - the Nexus 4 in 2012 and the Nexus 5 last year.
If the G3 indeed will be the Nexus 6 base model, then lovers of vanilla Android devices can again very well rejoice and more or less expect the following specs and features slipping right out of Google's box in the coming months:
A phablet-size Nexus
Samsung's Galaxy S5 boasts of a 5.1-inch screen and the iPhone 6 is rumoured to stretch its screen profile from 4-inch in the iPhone 5S to 4.8-inch. The bottom line is, flagship devices are upsizing their viewing window so Google has no choice but to ride with the wave of the future.
It is safe to assume then that a Nexus 6 modelled after the LG G3 is likely to show off a screen size not lower than 5.2-inch.
2K display resolution
The Galaxy S5 was initially rumoured to sport a 2K display panel, likely in 2560 x 1440 screen resolution, but the handset ended up being a 1080p device. It is also far off that Apple will push for 2K in the iPhone so Google can essentially steal the thunder off its two rivals by unpacking the Nexus 6 with Retina-busting and AMOLED-melting display panel.
Durable casing and element proofing
Google is aiming to correct the mistakes seen in the Nexus 4, with its fragile housing, that was slightly improved in the Nexus 5. In the Nexus 6, however, it is possible that the phone will be encased in a Liquidmetal-like material that Apple is rumoured to use with the iPhone 6.
Also, it is likely too that Google's signature phone will feature water and dust proofing, based on speculations that the LG G3 is packed with IP67 certification, which is the same element repelling standard that Samsung has introduced with the GS5.
Quad-core 64-bit processing chip
Qualcomm has recently unveiled two CPUs that analysts believe will power the high-end smartphones to come out starting in the second half of 2014 - the Snapdragon 805 and 810. Being the Google top-liner, the Nexus 6 is only expected to source its muscle power from any of the two chips.
Massive battery upgrade
One of the Nexus 5 drawbacks is its non-removable back cover that shields its 2300mAh battery from view. Users have no choice but to rely on this immovable power juice maker as Google is likely to retain its solid Nexus casing
But the tech giant will surely compensate by upgrading the next Nexus' battery rating, probably matching or even surpassing the Galaxy S5's 2800mAh energy generator.
Insanely great main cam shooter
The rear cam megapixel race for hero smartphones is now at 16MP, which is what the Galaxy S5 is boasting about. The Nexus 6 is likely to equal this numbers plus some optimal photo and clip capturing features. The core emphasis is to enable users to produce high-quality stills and videos then edit then prior to sharing with relative ease.
Google Now will certainly take the centre-stage during the Nexus 6 launch, highlighting the advent of hands-free smartphone navigation thanks to a more responsive and intuitive voice recognition. Google will further impress by porting the Always Listening feature that was popularised in the Moto X.
Fingerprint scanner is already in the iPhone 5S and the Galaxy S5. From persistent rumours, it's highly possible that the technology will be in an enhanced form once the iPhone 6 hits the market. Not to be outdone, Google will pair a Touch ID-like feature with an eye scanner that Samsung is reportedly equipping the Galaxy Note 4 with.
With an iris reader embedded in the Nexus 6 front-facing cam, the device will be the first to offer the toughest security protocol ever present in a mobile gadget.
The Nexus 6 is landing after Google would have unleashed its replacement for KitKat 4.4.2 at the I/O Developers Conference in June 24 and 25. The consensus is it would be Android 4.5, which could be Lollipop or another sweet label that Google has whipped up.
Solid price tag
The best thing about the Nexus 6 is the likelihood that Google will keep its price tag at a popular level. It is said that the iPhone 6 would debut $300 apiece on-contract. In turn, the LG-built Nexus 6 price range could be between $300 and $350, almost matching that of Apple's pricing model. But the Android flagship is hitting the market unlocked, which for many consumers is a joy as it unshackles them from contract obligations.
The Nexus 6 release date is pegged to happen between July and August 2014 or immediately after the Google I/O event while the LG G3, according to reports is set to rollout anytime in May or June of the same year.
