Very vague but good to know they worked on optimization and an internal rework. I wish he seemed more into the custom post-types because I think an ecomm solution should have a very tight integration with WP3 core and their post-types - granted that may push back a release of shopp 1.x but wpb2 works fine and is good for testing. Just wish he answered that differently but we'll see... the race is on between him and Dan Milward
