After a brief visit to the Strike Witches wiki, here's some more small details about the Strike Witches movie. Don't know where they get the sources for this stuff though:

-"It won't be a recap movie but get a all new story instead."
So no more of Miyafuji and 501 JFW? If that's the case, I definitely hope AIC's not animating the movie because they've butchered Strike Witches 2 so badly! I personally wished episodes 6-8 were part of SW1 instead.
-"At least 1 World Witch (the ones featured on EWACS will surely appear"
Seeing how which JFW hasn't been confirmed for the movie yet, I can't really post my opinion about this at the moment.
-"An enemy that will utterly embarrass the witches will appear"
Sounds like a lot of fun, so I have a little bit of hope. Let's hope it's not another neuroi bug.
-"There are no current plans to make it 3D, but they will consider it if people really want it."
I'm not a fan of 3D, so I'd say no (especially since this is an anime movie.)
I'm not sure what to make of the movie yet. But I'm still upset at how AIC screwed this up.
