Saw this early prototype of a new technology code named Flexible Integrated Linear Media that apparently we will see shortly in cameras, it has the following features and advantages:
Integrated sensor
- Allows upgrade to cameras sensor without buying a new camera
- Can purchase with specific dedicated behaviour (i.e Black and White) and ISO speeds
- No need to sensor clean as this is single use
Built in storage
- Storage for 12, 24 or 36 RAW images regardless of the sensor type and resolution
This really is quite cool, they are also talking about setting up a network of shops that you can take the cartridges to and they will do all your post processing and provide you with a set of prints for a minimal cost, will save heaps of time.
Also as they are all single use there is no need to full up your harddisk with images.
Can't wait for this to happen 
By the way got a photo on my crappy cell phone camera of the prototype, it is an interesting barrel design with the interface appearing as a brown piece of cellulose plastic, quite different from anything else I have seen:
