Apple may be engineering sweeping changes to its device line in 2012 that could be headlined by more than one iPad design. A questionable rumor from Digitimes had the expected March 2012 iPad revamp being just a slimmer, longer-lasting iPad 2 that would start small, early shipments in the fall. The "real" iPad 3 wouldn't arrive until summer 2012 at best, the sources claimed.
