Amazon.com: Godzilla vs. Biollante [Blu-ray]
Maybe if enough people buy it, someone will release The Return of Godzilla /Godzilla 1985.
I was shocked to see Godzilla 85 didn't even make it to regular DVD. And that movie still comes on TV (sometimes). I saw it on AMC a few months ago. You'd figure that would've been on DVD a long time ago.
