4 big things to watch out for in tech this week

It's a big week in the technology space as some of the world' biggest companies prepare to release flagship products at the IFA consumer electronics show in Berlin, Germany's capital city.

So this is what we are expecting so far:

Samsung's next smartwatch
Samsung unveiled its latest smartwatch on Monday as it looks to take on its U.S. rival Apple in the wearable space.
Samsung has held back on the price and availability of the Gear S2, but has a press conference scheduled at the IFA consumer electronics show in Berlin on Thursday where it is expected to give more details.

World's first 4K smartphone?
A Facebook page for Sony Georgia – which the Japanese electronics giant later said was fake – released details and images of the company's upcoming smartphones.
Sony is set to release three smartphones at the IFA on Wednesday. The Xperia Z5 series will include a "Premium" device that will have a 4K screen, potentially the world's first. 4K refers to the screen resolution and is sharper than ultra-high definition.

Next-gen TVs
IFA is also expected to feature the TVs that may grace homes over the next few years. One of the big announcements has come from LG which will be showing off what it is billing as the world's first "HDR capable 4K OLED TV" at the consumer electronics show in Berlin.

More smartwatches
According to leaks on Twitter, Motorola could unveil some new models of its Moto 360 smartwatch. China's Huawei is also expected to give more details about its smartwatch, a device it announced at Mobile World Congress earlier this year.
