Google is heavily rumored to expand its Nexus device lineup by introducing the first Google branded tablet in co-partnership with Asus. The tablet is expected to release this summer. But so far the 7-inch slate is still a mystery. However, it looks less likely to be a myth as images associated with the tablet have been leaked online.

Citing anonymous tipster, folks at PhoneArena posted on Wednesday computer screen images of what they claim to be press image drafts for the much-hyped Google Nexus tablet. The images show rear and front side of the Nexus tablet. At first glance, the tablet appears to be a larger sized smartphone (of the Samsung Galaxy Note variant) especially from the front side.

The photographed device has a white front, which looks like a big sized smartphone. However, the rear side appears to have two colors, black at the top and silver at the bottom. There are couples of sensors in the front including a larger bezel for video calling camera. There is also a larger hole at the back, which undoubtedly is the rear shooter. The Asus logo is also there at the back, confirming that the tablet is manufactured by Asus. Looking at the orientation and position the tablet is photographed, it is believed that the tablet is designed to operate in portrait mode ditching Android's favorite landscape tablet mode.

The tipster also provided some details on the spec sheet. The tablet boasts quad-core Nvidia Tegra 3 processor with 1GB of RAM. The tablet is also going to run Android 4.1 Jelly Bean. The new OS will be an update to Android 4.0 ICS just as Android 2.1 Eclair was an update to Android 2.0. Google is expected to feature 3D Google Maps in the new Android OS.

These are the first ever images associated with the Google Nexus tablet that have been leaked online. However, the reliability of the report is questionable as the images are blurry and can easily be faked. It is to be noted that speaker and proximity sensor is placed at the top, which apparently does not happen in case of tablets.

As far as the release date is concerned, the Internet search giant is expected to debut the Nexus tablet, if the tablet is actually real and not fictional, at Google I/O conference starting June 27.
