Sure, all of it is speculation right now and the iPad 2's rumored specs seem to change with the wind, but I bet that Apple has something up its sleeve -- and I don't think that it's a barometer.
I hope that the recent rumor that iPad will ship with an extremely weak1MP rear camera doesn't come true though. 1MP doesn't bode well for video and if true, you can toss out 720p video capture. Putting a low-res rear camera in iPad 2 would be a huge mistake and allow a whole generation of Android tabs to move in on its turf. iPad 2 needs to include a camera as least as good as the iPhone 4's.
I'm also starting to lose hope that the iPad 2 will have a Retina Display, although I still hope that Apple finds a way to pull it off. I wouldn't be surprised to see Apple settling on 1280 x 800 -- it'd be bump up from the iPad 1 and would match up better against the likes of Samsung, Motorola and Toshiba.
Let's all collectively cross our fingers that Apple finally comes to its senses and includes a removable memory card slot and Micro USB port in the new iPad. Since it's unlikely that we'll ever see a removable battery from Apple again, SD and USB would be huge steps in the right direction.
