The website madokamagicausa.com has appeared recently. The website currently leads nowhere, but if you do a whois search for the website you get some handy information. The website was registered by Aniplex USA, making it possible they plan on releasing the show here, although a similar thing happened with Darker Than Black Season 2 and that ended up going to Funimation. Aniplex USA had said they were negotiating for Madoka back in May.
I expect Aniplex will be announcing a DVD only release with $40 sets that only have 4 episodes each at Anime Expo. Or we could get lucky and someone who doesn’t price gouge their customers might release it.
