Apple Watch Series 3 launch details
File this one under 'Probably' - Apple is likely to unveil the Apple Watch Series 3 in the third quarter of this year.
Digitimes (hit and miss with Apple speculation in the past) writes: "The wearable device will be manufactured by Quanta Computer and feature better performance and longer battery life, according to a Chinese-language Economic Daily News (EDN) report citing market watchers.
"Currently, improving battery efficiency is Quanta's main task for the new Apple Watch and its other hardware will not see much change, the paper added."
Under Armour's big CES announcements
Under Armour used CES 2017 to launch three more sensor-packed shoes but it wasn't all about new kit.
Firstly Samsung announced that it will be teaming up with Under Armour to get the US sports giant's fitness apps built into its wearables such as the Gear S3 and the Gear Fit2. The fitness apps will be available as part of the Under Armour Connected Fitness suite including UA Record, MyFitnessPal, MapMyRun and Endomondo.
And secondly, UA revealed its Sleep & Recovery System, which combines some nifty new pyjamas with extra features on the UA Record app for improving sleep and overall athlete performance.
Carnival cruises embraces wearable tech
We've seen resorts and hotel chains using wristbands for digital payments and the like but no one has gone quite the extra (nautical) mile of Carnival Cruises, who announced its Ocean Medallion system over in Vegas this week.
The Bluetooth and NFC device, which goes live on ships in November, packs in a wealth of features including letting passengers get into their rooms, navigating the ship, ordering and paying for food and drinks, finding friends and family onboard, gaming experiences and more.
The Medallion, which comes in a range of designs, arrives in the post before you embark so you can start to personalise it.
Fitbit's new features
There were no new Fitbit trackers on show over in Vegas but the company did fine time to announce new features in the Fitbit app and the Fitstar personal trainer app, as well as updates to the Fitbit Blaze.
The Fitbit app has a new community section; think Facebook but less videos of cats. There's also new tailored insights and personal goal setting features.
The Fitstar personal trainer app now offers an enhanced personalised and guided workout journey, with recommended workouts and access to two certified personal trainers who will "guide you on your fitness journey"
Finally, the Blaze now packs in the cardio fitness level and relax guided breathing sessions that are available on the Fitbit Charge 2.
