I've noticed several conflicting reports about the release date of Haswell processors, so I wonder when the next Mac laptops refreshes will be. There are reports of MacBook Pros and Airs being refreshed next June, due to the Haswell release, but I am not convinced. Haswell will be available from June 2, 2013. However, there are reports saying that the processors that will be available first are the desktop processors and the higher-voltage quad-cores. Therefore, processors for the 13-inch MacBook Pro and for the MacBook Air will not be available so soon. There are reports of ultra-low Haswell processors being released only in Q3 2013. In addition, the Haswell GT3 GPU (which will bring much better performance) would be released only in Q4 2013. There will be new Ivy Bridge, low-voltage, processors being released meanwhile. Based on that, I guess that the timeframe for release of new Macs could be as follows: - MacBook Air refresh in Q1 2013, with new ultra-low voltage Ivy Bridge processors. - 15" MacBook Pro refresh in June 2013, with the new quad-core Haswell processors (the retina version being upgraded in June, but not sure if the non-retina version will be phased out). - 13" MacBook Pro refresh in Q3 2013, or when 35W mobile Haswell becomes available. - MacBook Air redesign in Q4 2013, when the ultra-low voltage Haswell is released. Due to the lower power requirements of Haswell, the MacBook Air could be even thinner. An IGZO display could be added, in order to provide retina resolutions and good battery life even in a thin design. Do you think this timeline is feasible? How do you think Apple will handle the MacBook release schedule due to these delays in the release of Haswell?
