I bought version 1 recently, so I was hoping for a MacWorld announcement, too. If you buy version 1 now, the upgrade to 2 will be free (according to their website). I'm pretty happy with v1, but I'm looking forward to some of the features and improvements coming with v2.
If you're considering using the iSight as a barcode reader, Delicious is far better than Pedia. It's very close in performance to a stand-alone scanner. It'll pretty much keep up while you grab a DVD, orientated it in front of the camera (there are target lines in an overlay on the live video), and pick up the next. It'll queue them up while it looks up info [from Amazon], artwork, then speaks the title.
