If you look, there are actually photos up on the internet of the Fairies, as they will be appearing. (Sorry - don't have a link right now, but I do remember you have to dig a little bit - it was in someone's blog thread.) They are beautiful and their clothes match the animation very well, especially Silvermist. Fawn and Iridessa are pretty close, too.
All of the trailers and Pixie Previews that have been running state, that it's a DVD and Blu-ray release. When you take a beloved character like Tink and create a whole new property from it, die-hard fans will either love it or hate it and that is a huge gamble to take financially. Guess they felt the tremendous expense of a theatrical launch might not balance the profit that they would gain from it, so they took the more conservative route!
