I'm sure it will.
It runs the iPhone OS so I'm sure it will.
My question is, will you be able to sync your iDisk with the file area on the iPad that iWorks will be accessing. If not, will you be able to use the iDisk app and download and upload files from that file area. I would hope one or the other would be available (and hopefully the first one). Another thing I'd like to see is being able to sync Notes thru MobileMe to the iPad.
