Rumors about MacBook Air delay

MacBook Air that was built using special version of Intel's mobile processing technology has been delayed in its updates. Power efficient versions of Intel processors are always shipped later than the standard processors. The delay in update of MacBook Air is caused by the same reason.
Power saving processor chips always reach late in market. Intel's new processor series "i" is a power sipping technology based chips and consume less power than other standard processors.
New processors are ULV (ultra low voltage). This technology is rated at 10watt of power that is less than standard mobile processor power consumption. Standard chips are rated at 35watt of power.
Now the "i" series processor core i5 will be rated at 18-watt, depending upon the graphic system.
No one knows for sure that Intel core i5 processor will be used in newer version of MacBook Air, even if Apple use the new processor then how it may choose for implementing the processor that will be with graphics or without graphics.
