We'll get to see first the second generation Nexus 7 and the Motorola X-Phone, likely the bearer of Google's Key Lime Pie, prior to the anticipated release of the Nexus 5 smartphone, a new report said.

Despite the widespread rumours that Google intends to battle it out with Apple and Samsung in Q3 2013 via the Nexus 5, Stephen Schenck of PocketNow is convinced that the internet search giant will hold its punches and stick to its game plan.

That plan includes a major refresh of the Nexus 7, its screen and CPU set for bump ups that will dwarf the planned spec upgrades of Apple's iPad Mini 2 and Samsung's Galaxy Note 8.0, and the global rollout of Key Lime Pie or Android 5.0.

Mr Schenck believes Google will allow the X-Phone to become the first handset that will flash the new mobile device prowess developed by Google engineers and to be flashed with the KLP.

Experts are in agreement that the new Motorola smartphone will be previewed by Google using its I/O Developers Conference on May and KLP will be part of the whole package.

This is a high possibility, Mr Schenck said, adding that "Google is not a company that needs to rush things."

He insisted that while the Nexus 4 now faces stronger competition with the entry of Samsung Galaxy S4 and the expected arrival of Apple's iPhone 5S and its cheaper version, the stock Android smartphone is "still a highly capable smartphone by most estimations, and there hasn't been the arrival of any new killer feature which it lacks."

The safest bet for a Nexus 5 debut is around the same time that Google pushed out the Nexus 4, which is the 2012 holiday quarter.

By that time, Google would have realised its pledge of delivering insanely great features for the Nexus 5 plus the added bonus of shipping out the handset with speed and with ample supply.
