After iOS 5, what does "Sync" cover?

[Mobile923]

Okay, I'm understanding under iOS 5, iCloud takes the following off iTunes' shoulders:

-Device Backup
-Camera Roll, App Data, Settings

So now, The only thing leaving for iTunes Sync to handle is:

-Movies/TV Shows
-iPhoto Albums

Now, with iTunes in the Cloud / iTunes Match, my music library is now handled with the cloud... right? But what about Apps in iTunes in the Cloud?

Can I finally delete iOS Apps off my Macbook Air?
