Motorola reportedly sent exclusive invites for a July 11 event that could see the Moto X unveiling this week but new reports insist Android fans should not expect a major release date to happen.

The chance is slim, as well, that Google will finally unwrap the rumoured Nexus 5 as confirmed specs for the Moto X are too remote to represent the supposed Nexus 4 upgrade, experts said.

Last week, tech world veteran Leo Laporte floated the idea that Motorola is planning to unveil the Moto X in the few days ahead, basing his conjecture on a special invitation sent out by Motorola's Guy Kawasaki.

The alleged occasion seems an intimate gathering, limited only to 50 tech journalists that will be herded to Google's Mountain View HQ.

Since it is all but official that the Moto X is not the Nexus 5 and it will not be on the latest Android, not Jelly Bean 4.3 nor Key Lime Pie, on release date, Mr Laporte speculated that Motorola plans to finally out the handset, which according to analysts is coming this month or August.

Citing an unidentified source, however, CNET reported that something different is coming down on July 11.

"We're told by a source that Motorola has something else to share with journalists. No more details are yet forthcoming," the tech site declared.

The report came out following Motorola's hint last week that the Moto X, previously known as the Motorola X-Phone and touted earlier as the game-changing Nexus 5, will be made available with options to customise on users' preferences.

Yet of hopes of sky-is-the-limit phone features for Android users were quickly dampened when a follow-up ABC News clarified that Moto X personalisation is actually limited on case colours and engravings, which are custom-options readily available to other phone brands, especially in the feature phone class.

This latest disappointment adds up to the Moto X specs that turned out as far from being high-end or Nexus-like. Instead, the device will be powered by the tandem of a dual-core CPU and Jelly Bean 4.2.2, with the distribution initially limited in the United States.

Australians though would likely have access to the Moto X in the immediate weeks after its release date on the strength of reports earlier this year that Telstra, the country's dominant telco, was a close partner in the so-called Google-Motorola X-Phone Project.
