What is the most solid indication that Nexus 7 2 is touching down soon? For many, it's the sliding price marks of the first Nexus 7, which Google distributing partners have discounted by as much as $US50, new reports said.

As if to prepare the way for the rumoured August release date for the second-gen 7-inch stock Android tablet, U.S. retailers are cutting down its predecessor's price tags, providing more reasons for tablet buyers to clean off the shelves before the replacement arrives.

Analysts said, that is exactly what the Google ploy is all about - wiping out the remaining Nexus 7 inventories in order to focus consumers' attention to the more powerful Nexus 7 2, which reports said will sport a 1080p screen resolution plus a quad-core capable CPU of the Snapdragon class.

The 16GB Nexus 7, for example, is now up for grabs for only $US180 while the 32GB kind is flashing a $50 price off, according to Gotta Be Mobile.

The latest move indicates that Asus, Google and their selling partners are attempting to rush the clearing of old stocks and cash in as much as possible before shipping out the freshly minted Nexus 7 2, production of which is believed to be already underway.

Repackaging old products in more attractive prices is standard marketing practice for many firms so as to do away with the previous models and fix consumers' attention on the new build, experts said.

This approach Google also applies with the rumoured impending Nexus 5 release date. This week it was reported that UK retailers have pulled out the Nexus 4 from active display while Google Play Store signalled stock outs of the same device since last week.

Analyst quickly read the Google body-language as the firs stage of preparation for outing the Nexus 5, which is almost the same case even for iPhone maker Apple. The tech giant either shrinks the price of old iPhone models or packed them with telco contracts at lower cash outs to clear the way for new editions.

As for Google, numerous reports insist that the company is pushing out a fully-improved Nexus 7 2 with its impressive specs designed as the ultimate iPad Mini 2 killer.

On its release date, pegged for first week of August, the 7-inch tablet is seen as the first Android slate to showcase Jelly Bean 4.3, which is matched by top-notch components and a starting price of no more than $US220.

Also, it is highly likely that Google will uncloak the Nexus 7 2 on July 11 prior to its commercial debut a few weeks ahead, reports said.
