Apple has informed developers that they can now submit 64-bit iOS 7 apps for App Store approval; however, at this time those apps will not run on iOS 6.

You can submit 64-bit apps for iOS 7 today that take advantage of the power of iPhone 5s. Xcode can build your app with both 32-bit and 64-bit binaries included so it works across all devices running iOS 7. If you wish to continue to support iOS 6 then you will need to build for 32-bit only. Next month we will be making changes that will allow you create a single app binary that supports 32-bit on iOS 6, as well as 32-bit and 64-bit on iOS 7.

The iPhone 5s is the first smartphone to utilize a 64-bit processor. Apple is promising up to twice the CPU and graphics performance for almost everything you do on the device. You can take a look at some early benchmarks here. More benchmarks will be posted once the device is released on September 20th.

it seams to me that App makers will stay with 32bits Apps making it easy on themselves! smaller Apps which will work on all devices and bring in more money then writing only 64 bits Apps or 32/64 double size Apps.

This is not exactly how binaries work. A simple way to explain this is "more information" passes on each CPU clock cycle. Binary size does not really change significantly.
