Sony PS4 is called Xperia PS Z

Why not? There is the fabulous Xperia Z, water proof, superb camera, and perhaps the flagship saviour of the entire Sony clan.

There is the Xperia Z Tablet. Super thin, top performance. Made in Japan.

So surely Sony MUST come out with a new clan of Z. A triumvirate of tech wizardry.

If Microsoft has the all seeing eye 2 years ago to unify their whole system, Xbox, Windows Phone and Desktop OS into a supreme Super 8 kind of trinity, then perhaps Sony should have this futuristic view.

Sony is a powerful beast. They have a very strong camera department. If they can gather enough momentum and unification in their devices, ie. phones, camera, tablets, gaming consoles - wow a miracle could happen.

The competition:
Microsoft has the trinity of triple playing console, OS, and phone.
Apple in their own system - no console.
Google is just phone OS. No gaming console, no real defined OS.
How about other possible players?
Nikon? Great camera, that's it.

Canon! Camera and Printer - converged and they have had a wonderful run since the beginning of the digital age of photography. But can they move further? Shouldn't they have an Android camera and printer to go forward? I think they should. NOW.

Samsung has conquered the phone world. Tablet. No console. But look at their other devices. Here devices mean anything nowadays that has some electronics and some basic brain CPU power. Remember the notion of "IP everywhere"? "IP on everything". Look at Samsung carefully. They have drones of devices, huge robotics. Yes! Refrigerators, microwaves, washing machine, dish washer, dryer, electronic door lock (PIN, bio, NFC capable). I bet vacuum cleaners and those robotic floor sweeping machines too. They should be eventually connected somehow. If there isn't a wifi they should have some sort of NFC system, or low-powered Bluetooth. Your vacuum cleaner could be fitted with GPS too. Your fridge is connected via Ethernet and it will notify an order for eggs and milk when they run out, since these are surely the easiest positions in the fridge to have some way of checking the level of milk and eggs. Perhaps rice too.
Coffee machines.

Hwaiting! (Ha Ji Won)

What about Seoul, Korea? LG too is big in the white goods, household goods. Refrigerators and microwaves.

Samsung has jumped the huge leap again with the defining Android Galaxy Camera. If Canon and Nikon does not take note of this in their top management's thinking, they might be going the days of Hayes.
