We are over run by iPhone 6 leaks, photos, parts you name it. Apple is expected to reveal the iPhone 6 September 9 at an event. Apple is since several years not able anymore to keep secrets. Their network of suppliers in Asia is swiss cheese for leaks of hardware parts and prototypes.
The situation around the rumored iWatch is though completely different. We have no leaked iWatch part. We have no leaked prototype. All we have a rumor reports, patents and suspicious hires. It is save to say that Apple is working on wearable products including an iWatch. Because of the lack of leaked parts I am leaning towards the assumption that Apple is again not ready to release the iWatch this year.
We had the same situation in 2013. The iWatch rumors have been intense. Even analysts have pointed to a Q4 release of the iWatch and nothing happened. You can review the iWatch rumors in 2013 in our extensive iWatch History report.
In my opinion Apple did not solve the issues yet that plague smart watches: low usability, big size and short battery life. Apple is under a lot of pressure to do the iWatch right. They cannot really afford a failure. Other gadget companies like Samsung, LG and Motorola are not afraid of failure. They just put it out and see how it goes. It does not go well for smart watches that have released so far. The new Android Wear is going to push even more smart watches on the market that are incrementally better than the current generation, but still not solve the fundamental problem of offering mass market appeal.
