Either way, we will be seeing a huge flood of app updates in the coming weeks. Get ready to see a bunch of app updates every time you open the app store.
I think more about how much extra HD space will be used to upgrade the images. I really hope they (Apple) give a option to buy something larger than 64GB. An HD movie can be over 5GB each. An HD game must be vast.
I'm sure apple will be trying to sell iTunes Match for the simple ability to have all you music with you without using any of the iPads space via iCloud. If you go that route you only need to worry about spece for apps and Movies.
