DigiTimes continues to share rumors of new iPads coming in March of next year, and says that in order to meet demand, Apple will start stockpiling as many as 2 million units by the end of this year. Apparently, there are two designs in the works, code-named J1 and J2. Both have a higher resolution than the iPad 2, as well as different specs and sizes. Since things are still at an early stage, apparently Apple hasn't yet decided which model will be released. It likely depends on availablility of components, production costs, and market.
