The LG-made Google Nexus 4 is still a very popular smartphone, but rumors of a Nexus 5 phone are piling up in anticipation of the next big thing.

The Nexus 5, however, is so elusive that most reports don't even agree on which manufacturer will get to make the smartphone. Some suggest the handset may make its debut alongside the new Android 5.0 Key Lime Pie at the Google I/O conference in May, but considering all the current rumors, speculations and "what ifs," it's unlikely the smartphone will launch anytime soon.

Many concepts and allegedly official renders of the Nexus 5 are making rounds, suggesting a number of cool specs such as a 5-inch or larger screen, 3GB or even 4GB of RAM, a 5,000mAh battery and other such dream features that seem taken off an Android wish list. Truth be told, most if the information currently available regarding the Nexus 5 essentially consists of such fantasy specs and fan-made mockups.

A debatable Nexus 5 official render emerged recently from Dutch tech website MobiLeaks, which claims to have the real deal. This mockup features an LG creation with amazing specs: a 5.2-inch Full HD OLED display with a 1920 x 1080p resolution, a quad-core Qualcomm Snapdragon 800 processor clocked at up to 2.3GHz, a whopping 3GB of RAM, dual cameras - a 16-megapixel rear-facing camera and a 2.1-megapixel front shooter - and a powerful 3,300mAh battery.

While it all sounds very exciting, this rendering prompts some inevitable skepticism. Many of these features may be current technology, but they have yet to rock devices on a large commercial basis. Most current gadgets packing Qualcomm chipsets are still on the Snapdragon 600 processor at best, while many current smarphones are still sporting 8-megapixel cameras. No current device packs more than 2GB of RAM and only a few devices boast batteries over 3,000mAh. The Motorola Droid RAZR MAXX notably packs a 3,300mAh battery, but the new Nexus would have to make a great leap from the Nexus 4's 2,100mAh battery.

The source claims this is an official render of the Nexus 5, but at an early stage of development, which means it might still see some tweaks before the final version is ready. On the other hand, when something sounds too good to be true it usually is, and there's a good chance that this render is a fake. Does it seem real to you?
