In the “It had to happen” Department, here is a little bit on information: Canon has submitted a patent application for what looks like a touch screen Man-Machine Interface for a DSLR camera. Of course, this is not exactly new technology (it’s everywhere from point-and-shoot cameras to mobile phones) but a patent from Canon probably means that they are very serious about it in the near future.
