iPhone 5S launch: What we know

The iPhone 5S and iPhone 5C are expected to be unveiled by Apple after months of feverish speculation.
What we know:
The normally secretive Apple has invited tech journalists to an event at its Cupertino headquarters in California, as well as satellite events in Berlin, Germany; Tokyo; Japan; and Beijing; China.
Apple unveiled the iPhone 5 around this time last year, and has never waited more than 12 months to update an iPhone.

What we expect:
Anything other than the launch of two new smartphones the iPhone 5S and a budget version the iPhone 5C would represent a major shock.
The flagship iPhone 5S should feature a fingerprint scanner on the home button, a 12 or 13-megapixel camera and a more powerful processor.
It is also likely to be available in gold, which like the iPhone 5C is a nod to the Chinese market.
The iPhone 5C represents Apples first-ever budget product, and should be available in a range of bright colours in another departure for the usually monochromatic tech giant.
The previously mooted iOS 7 will also be officially previewed, with chief executive Tim Cook describing the new operating system as the biggest change since the introduction of the iPhone.

What we dont know:
If any of the above is actually true, and whether Apple the worlds biggest company with a market value of $460billion (£292billion) will scupper its own next generation phone with a budget model designed to be the silver bullet against cheaper Android devices.
