Smartphone manufacturer's website confirms both devices' existence.
Sony has mistakenly confirmed the existence of two flagship handsets on its website, with official press shots depicting both the Xperia Z and Xperia ZL smartphones.
Speculation has surrounded a 5-inch handset named the Xperia Yuga, which is said to be the production name for the Xperia Z. The image above confirms the Sony Xperia Z (on the left) will be an Android handset, with the previously seen oversized power/lock key situated on the side.
The Xperia Z is rumored to feature a 1920 x 1080 resolution, a glass front and rear, a microSD card slot and an HDMI port. It runs on Android 4.1.1 Jelly Bean, powered by a 1.5GHz quad-core processor and 2 GB RAM, accompanied by a 12-megapixel camera.
As for the Sony Xperia ZL (on the right), it's said to be the Japanese technology company's rumored Odin handset, which sports a 1GHz Qualcomm Snapdragon MSM7227A CPU, an Adreno 200 GPU and a resolution of 480 x 320. It runs on Android 4.0.4 Ice Cream Sandwich.
Sony is aiming to ship 50 million Xperia smartphones during 2013, with around 35 million units being sold in 2012.
