Reports about the Google Nexus 5 and the Android 5.0 Key Lime Pie continue to circulate for a few months now. Likewise, with the almost near release of the Android 5 and the device, the attention slowly shifts to their future counterparts.

Ever wonder how the Google Nexus 6 and Android 6.0 milkshake will look like?

The concept phone was called the Google's "X" phone. Now, this was not to be confused with the recently announced Moto X phone. According to reports, Google and Motorola were also working on another handset, and this could possibly be the Nexus 6.

The idea behind the Google Nexus 6 featured Android 6.0 Milkshake. As the device will most likely be released next year - with so many releases from the tech giant already this year - analysts said it is best to expect the upcoming Nexus to have a different display and the latest Android interface with it.

According to this concept, the Google Nexus 6 may feature support for spatial gestures. It also showcased an edgy back side complete with the signature "X" which has been steadily identified with Motorola's new set of handsets. The designer indicated that the device will comprised materials that are both composite and flexible. The X offered a new milestone for the device. The same way that Fabula was used to identify with Nokia.

This version of the Nexus 5 included an HDMI out and a flexible 4.6-inch display. The phone has the same Kevlar finish seen on the latest Motorola DROID RAZR HD. The device measured 8.5 mm thick, offering a resolution of 1280 x 768. Other specs included 10-megapizel camera, NFC, GPS support, wireless charging and a 2-megapixel front camera. It also came with a gyroscope, a compass and a barometer.

There were reports indicating the release of the Google Nexus 5 and Android 5.0 Key Lime Pie around September or October. The release of the device along with the new Android OS will serve as the basis for comparison for these upcoming tech updates. Google, by far, was successful with releasing several versions of the Nexus, the latest with the second-generation Nexus 7.

Can the tech giant replicate its success on all platforms including mobile and operating systems?
