I can't really see that there will be much of an update, if any to the next iPad. If this supposed iPad 'Mini' exists, and it doesn't coincide with the iPhone's 5 release, I could maybe see that being added to the lineup next March.
If the 'Mini' is released in October, and there is an update to the iPad next year, then I think the changes will be incremental. Maybe a bump up to an 8MP back camera, and a 1MP front facing camera. Screen will be the same, internals will be pretty much the same, except maybe a 1.2GHz dual-core CPU. Doubt it will be quad-core, just yet. The 30 pin dock connector might change to the one the next iPhone is supposed to use - I guess this will happen with the iPod's, also. The 16GB might be dropped and a 128GB version will be added, due to the Retina screen and apps needing to be a higher resolution.
BUT WHAT DO I KNOW.
