The one I watched was just subbed. I imagine it's going to be like that for the other movies. However, the subs used the English names as opposed to the Japanese names.
I don't know about a release yet. There's apparently going to be a DVD+Blu-ray release in Japan...MAYBE in Europe, too? I think I heard Germany was getting one? It's still pretty unclear, you should probably check Google or Court Records.
