What does this mean? "When purchased, this movie will not be available from iTunes in the Cloud" In the iTunes Store, specifically in regards to movies, what does this mean? "When purchased, this movie will not be available from iTunes in the Cloud" 

I'm seeing it on the individual movie page for the new Indiana Jones bundle 

Can the movie only be downloaded once?

Can I download the 720p version now, and then download the 1080p version later?

I don't really care about streaming from the cloud; I have a Mac mini setup as an iTunes "server", I'm just concerned that I'd only be able to download one version, one time.
Yes, some studios only allow a movie to be downloaded once, so you see this message. I'd wait until you're able to download the 1080p version.
