It's clear that Apple is rebuilding MobileMe before it expires in a few months. Apple could have launched iCloud with all the features of MobileMe, but look at what happened when they did that last time in the transition from .Mac to MobileMe.
I think that wiping the slate clean and making sure they make each feature great on its own, one at a time, is the best way to get iCloud to reach its potential.
We'll no doubt see iDisk or an equivalent replacement coming in to the iCloud family soon enough. Safari for Mountain Lion will sync tabs to iOS and the keychain is but a small step to syncing all of a user's Safari experience between their Macs and iOS devices.
