You know, I do not know why Apple would feel motivated to roll out a Gen 2 product at this (that) point. There is no real competition and the market isn't nearly saturated to the point for a "prime the pump" upgrade. A lot of makers (cars, TVs, cell phones) could give us their R&D department's laundry list of new features well before they typically do. The marketing wing of the corporations, however, want to maintain vertical product profiles and to only give out enough new features to keep the market humming, but not so much that they potentially have a few years of "nothing new here, time to move one to something else" conditions.
My prediction: If you want an iPad type device and have the need, buy it now. There probably won't be much else hardware wise from Apple before next spring, if then. When you see a new product hit the market (Slate, Droidpad, whatever) then you can start holding your pennies for the next Apple pad device.
