According to Concord Securities analyst Ming-Chi Kuo Apple will refresh their MacBook Air line to include Thunderbolt technology previously introduced in Apple’s refresh of the MacBook pro line and also Intel’s new low voltage Sandy Bridge i5/i7 processors. According to Kuo the next generation MacBook Air, both 13.3 inch and 11.6 inch, will begin production in early May and will end up being released sometime in June.

AppleInsider has the full report on Kuo’s reliable predictions below:

In moving to Intel’s 32-nanometer (nm) Sandy Bridge architecture, the mid-2011 MacBook Airs will jettison two-year-old Penryn-based 45-nm Core 2 Duo chips for the chipmakers’ new line (below) of low-voltage and ultra-low-voltage Core i5 and Core i7 chips, which sport between 3MB and 4MB of Smart Cache and support a theoretical maximum of 8GB of internal system memory.

Should Apple follow its current trend of using ultra-low-variants for the 11.6-inch MacBook Air and low-voltage ones for the 13.3-inch models, consumers can expect to see new 11.6-inch MacBook Airs sporting 1.4GHz to 1.6GHz Core i5 and Core i7 chips and 13.3-inch MacBook Airs with 2.10 and 2.30GHz Core i7 processors.

Overall this looks like a very large update to the MacBook Air line that will definitely be worth updating for.
