"Our sources are saying that not only will there be a newly designed iPhone coming in the fall, but there is going to be a new entry into the iPad family as well. As hard as it might be to believe, the new tablet is said to sport a double resolution screen (2048 x 1536), and will be dubbed the “iPad HD.” The idea behind the product is apparently that it will be a “pro” device aimed at a higher end market — folks who work in video and photo production possibly — and will be introduced along side something like an iPad version of Final Cut or Aperture. This product is specifically said to not be the iPad 3, rather a complimentary piece of the iPad 2 line. Think Mac Book and Mac Book Pro."
So this probably means no less than 600$ for the 16GB version
