Thinksecret is reporting that we should expect the 13.3â€? MacBooks (the new iBooks) as early as May – we’d originally heardÂ June -Â arriving in both a single and dual core version. In addition, they note that the new MacBooks will replace the 14â€? iBook and 12â€? Powerbook, while Apple will continue to sell the current 12â€? iBook, albeit in limited quantities. Lastly, the new 17â€? Macbook Pro is rumored to emerge around the same time as the new MacBooks, sporting a brighter screen and of course Intelâ€™s new Dual Core chip.
