It has been a crazy week, full of high-wattage events and breathless news releases.

It can get a bit difficult to keep track of the hundreds of articles that came out over the week, so we've rounded up the best and most important stories for you, right here.

Sony unveils Xperia Z2 with 4K ultra-HD video recording, 20.7 MP camera; coming in March

Barcelona: Sony Corp. is borrowing innovations from its audio and camcorder businesses and incorporating its new Xperia Z2 smartphone with noise-cancelling technology and ultra-high-definition video recording.

Noise cancellation works with an in-ear headset sold separately, while the Z2's built-in camera can capture video in so-called 4K resolution, an emerging standard that offers four times the details as current high-definition video.

"With Xperia Z2 we have taken our premium Z series to the next level, delivering unique experiences that only Sony can offer," Kunimasa Suzuki, Sony Mobile's president and CEO, said in a statement.

The Xperia Z2 is waterproof, like the Z1 phones, and its screen is slightly larger, at 5.2 inches diagonally instead of 5 inches.
