Sony to stop making Cameras ?

The answer is quite easy:

Some time between now and the end of the universe or the end of time.

I'd go even further and say somewhere between now and the end of humankind.

So I'd advise you to jump ship, sell all your equipment and wait for the end to start telling people that you knew. There is the possibility to just hold your feet still but it's quite risky and I'm not sure if you really wanna take that risk.
