Better more battery efficient processor like they always do with their handhelds. This isn't even based on the latest from the Tegra chipset. I'd be a fool to just buy the first version when I know their history. If they don't update in a year or two from now or I see a can't miss deal I'll buy this one.What can they revise? It's a tablet with controllers on the side. They likely don't make it smaller. New controllers? Internal memory isn't important with an SD slot.
