Google is widely expected to release a brand new Nexus smartphone manufactured by Motorola sometime this year and new leaks give us a look at details such as the release date and pricing -- here's a look at what they are.

According to the folks over at PhoneArena, Google will release the Nexus 6, reportedly called the "Nexus X" internally at Motorola, without any announcement. What's more, the Nexus X should release before the end of October.

Google has done this in the past. The Mountain View-based search giant released the Nexus 5 handset last year straight to Google Play without any reveal event typical of flagship phones like the iPhone or Galaxy S.

PhoneArena also points out that, although many publications, including Latin Post, have referred to the smartphone as the Nexus 6, copyright issues will most likely have Google name the handset Nexus X. Other codenames for the new Nexus phone in the past have included "Shamu."

Then we have a report from TKTechNews, where the website shows off screenshots from two retailers that seem to have accidentally posted a listing for the Nexus X. Both Fnac Portugal and Best Buy have since taken down the pages, but not before TKTechNews was able to grab some specs.

According to the Best Buy listing, the Nexus X will sport a 5.9-inch 2K display and feature Android 5.0 (apparently called "Lemon Meringue Pie"). Fnac's page, however, shows some discrepancies, including claiming a 6.3-inch display, casting doubt over the credibility of the screenshots.

Pricewise, Fnac says the Nexus X will cost 419.99 euros and Best Buy prices the Nexus X at $499.99, although for some reason it's paired with a two-year Sprint contract.

TKTechNews does state that it has been informed that Fnac's postings have been known to be inaccurate in the past.

Remember, neither Google nor Motorola has confirmed anything, so until the Nexus X actually releases (thanks to Google's secret launch strategy), there's no way of knowing what's inside.

Still, the details that have emerged from leaks fall in line with what has slowly been trickling out into the technosphere. The Nexus X could also come equipped with a quad-core Qualcomm Snapdragon 805 processor clocked at 2.7GHz, a 13-megapixel rear-facing camera, and 3GB RAM.

Although there was significant suspicion that Google might be dropping its Nexus lineup for a more high-end "Silver" program, head of Android engineering and the Nexus program at Google Dan Burke told ReadWrite in June that Nexus isn't going anywhere.

"When we are working, there are sort of two outputs. We're building a Nexus device and we're building the open source code. There is no way you can build the open source code without the phone or tablet or whatever you are building," Burke said.
