Google has reportedly roped in HTC to make two 2016 series Nexus phones, codenamed M1 and S1, popular phone-spy Evan Blass had said on April 27. Now, more evidence related to the upcoming devices has surfaced online.

Android Police, citing multiple reliable sources, has claimed the "M" in the "Nexus M1" actually stands for Marlin and the "S" in "Nexus S1" is termed Sailfish.

This is in line with Google's way of christening its devices based on marine animals. Last year, Google's LG Nexus 5X and Huawei Nexus 6P phablet were internally known as Angler (a deep-sea fish) and Bullhead (a shark species). Interested readers can take a look at the list of all Nexus series devices with official code-names, HERE.

As of now, there is no word about what hardware they will be coming with. But, the devices are all but certain to come with the latest Android N series OS out-of-the-box, which is slated to break cover in the third quarter of 2016.

Last week, Google released Android N Developer Preview OS v2.0 to registered software programmers. It was found that the firmware supports 3D Touch. So the new HTC Nexus series phones are likely to come with pressure sensitive display, which was first introduced in Apple's iPhone 6S series.

For the uninitiated, 3D Touch technology enables the device's screen to intuitively sense the difference in finger pressure to enable gestures like "Peek" and "Pop". Users can peek in and out of content without losing their place. They just need to press the screen lightly to get a Peek at a photo, email, web page or other content, and if pressed a little harder, they content will pop open.

Once launched, HTC Nexus 2016 series will join the ranks of Android-based Huawei Mate S and Meizu Pro 6 to boast 3D touchscreen technology.
