Well, there are good reasons to keep it and I would be disappointed if it went.
But, Apple are known to revolutionize consumer behavior by forcing changes that many people don't like. So far it has worked for them, and people have grown used to the changes (i.e. no optical drive, no flash, no blu ray), and most people recognize the wisdom of their ways after the fact. They may well kill it if they want iCloud to be the primary media content deliverer, and the only way people will have access to all their files on the road. Personally, I think it would be too soon for it to happen this year, and it would be a mistake. The iCloud model is just birthing, and many people would be left out in the cold, i.e., international's, traveller's, etc. The day may come when it disappears, but a lot of changes need to take place before people like me don't mind.
