Intel rolled out its fourth generation of Intel Core processors this week (the chips formerly known as Haswell), and vendors have wasted no time getting word out about their plans - Sony, for example, has already introduced new ultrabooks with the new chips inside, though they're not expected to ship quite yet. We won't know for sure what Apple has up its sleeve until next Monday, when Tim Cook takes the stage, but MacBook Airs seem certain for a Haswell refresh, according to Mark Gurman at 9to5Mac.
