Gundam Unicorn will be released March 12 for $49.99 as an Amazon.com exclusive for two months.
The whole episode is only 60 minutes long, which means that is quite a price tag for a 60 minute "movie". The pricing seems more in line with what the Japanese pay for OVAs, which can be as much as $50 for one 30 minute episode. I guess if you look at it like that we are getting a great deal.
Though I am sure after the two month window has passed you will see this thing drastically lower in price.
