While we may have to wait until the late summer or early fall to get new versions of the iPhone and the iPad, it seems that Apple (AAPL) does plan on at least refreshing its MacBook lineup this spring. Digitimes reports that Apple plans to release “its new MacBook products at the end of the second quarter,” which means we’ll likely get fresh versions of both the MacBook Air and the MacBook Pro by the end of June. Digitimes‘ sources also claim that demand for Apple’s current-generation MacBook Pro has been below the company’s expectations despite strong interest because the notebook’s high price is scaring consumers away.
