What's the difference between the Asus Transformer Pad Trio and the Duet?

I've been hearing a lot about the trio but just recently started hearing about the duet, what's the difference, I get nothing when I look it up online. Please explain the difference based on how they're marketing it, as well as the specs. Thanks!
