Will they be released over a short period of time in the US, as they were here?

Only speaking for Portland, OR, the three films will all get released here this year. The second came out yesterday; the first is still playing locally. But Portland can have offbeat scheduling -- it's one of the few United States cities that still sometimes has a film stick around for months and months -- so I don't know how much that's being tried elsewhere in the U.S.
