The second Nexus 7 edition was unveiled this week boasting of upscale components and capabilities but one analyst is far from impressed, insisting that the stock Android tablet will be eclipsed by the Moto X on release date.

It might be that "the second-generation Nexus 7 showcases Retina display and wireless charging," this week, according to Ming-chi Kuo of KGI Securities, but he stressed that there was nothing new to what Google and Asus has delivered.

"The user experience is little changed as compared to other Android tablets ... it is also more expensive due to higher component costs," Mr Kuo was reported by Apple Insider as saying in a latest research note.

The excitement generated by version 2.0 of the 7-inch Jelly Bean 4.3 tablet will not match the actual sales that it would realise from August through the end of December 2013, the KGI analyst predicted.

By the end of the year, Google will only ship out four million units of Nexus 7, tops, Mr Kuo said, his numbers representing a big slip from earlier market forecasts that the vanilla Android slate would attract some seven million unit sales to wrap up 2013.

Clearly, innovation was absent in the product, its overall features and design merely reflects the first Nexus 7 release by Google in Q3 2012, Mr Kuo observed.

Yet while the tech giant is in for a crash landing on its 7-inch tablet thrust, which Google hopes will eventually morph into an iPad killer machine, the company could pull in a surprise with the Moto X, formerly known as Motorola X-Phone.

As the first flagship resulting from the collaboration of Google and Motorola, since the former acquired the latter last year, Moto X would signal the consolidation of the Android campaign to dominate the mobile device market across the board.

Likely playing the role of harbinger of great things to come from Google, the Moto X will lead the tech giant into a path, in which "Google is expected to shift more resources into hardware," Mr Kuo said.

"By integrating hardware and software to speed up innovation and by launching new flagship models, Google could come to be regarded as a beacon of superior product design in the chaotic Android camp," the KGI analyst explained.

As for the Moto X actual performance for 2013, the handset will likely account for 5.5 million units shipments by the end of the year, Mr Kuo said, adjusting from his earlier outlook of merely 3.5 million units.

Relying on the following features and spec for higher sales figures - a dual-core processor, a 4.5-inch screen, always-on voice command, a 5M main cam and Jelly Bean 4.2.2 - the Moto X is set for unveiling in August 1, with its immediate availability to follow shortly.
