After rigorous testing over the summer and three developer previews later, Google is finally set to launch the final version the Android 6.0 Marshmallow. If the latest confirmation from an Android-based website is to be believed, a handful of Nexus devices will be receiving Google's next-gen mobile operating system next week.

According to Android Police, the Android 6.0 M will be available for the LG Nexus 5, Motorola Nexus 6, HTC Nexus 9, Asus Nexus 7 (2013) and Asus Nexus Player starting Oct. 5.

It has also been confirmed that Android 6.0 M won't be making its way to the LG Nexus 4, Asus Nexus 7 (2012) and Samsung Nexus 10 tablet. Google's decision to overlook the three aforementioned Nexus devices wasn't a matter if they could run Android 6.0 M properly, but rather if it was worth the company's time and effort to support devices released way back in 2012.

It should be worth mentioning that the planned release date doesn't mean all users of the newer Nexus devices will actually get the Android 6.0 M on Oct. 5. Of course, users can always choose to update their Nexus devices manually, but since they've waited this long already, a few more days certainly won't hurt. Oct. 5 will also be the date when the final Marshmallow code will be brought to the Android Open Source Project.

Google will most likely announce the official Android 6.0 M rollout schedule during its media event on Sept. 29, wherein the company will unveil the LG Nexus 5X and Huawei Nexus 6P.

This recent report has corroborated with a previously leaked FAQ page from Telus.

According to the Canadian mobile carrier's releasing schedule, Google's next-generation mobile operating system will start seeding to the LG Nexus 5 and Motorola Nexus 6 on Oct. 5, although the date might just be applicable in Canada.

LG Nexus 5 and Motorola Nexus 6 users in the U.S. shouldn't fret since Google's software updates usually come sooner in the country.

Aside from containing the expected visual and performance improvements, Android 6.0 M updates "Android Pay" and "Google Now" while carrying a new standardize fingerprint sensor and support for backup data, Android Pit reported.

It has been well-documented that Google uses its Nexus devices to debut the latest in Android technology. The Nexus brand is widely thought to deliver nothing but the "purest" Android experience. Handsets under its belt are free of bloatware and third-party applications from cell phone carriers or other Android-based device makers. Nexus devices are also the first to receive software updates from Google.
