Apple fans may have to wait a little longer as the release date for a Macbook Air 12-inch Retina display model is allegedly pushed back to 2015, according to reports.

Rumor mills claim that the delay is caused by processor supply constraints in Taiwan.

However, the regular 11-inch and 13-inch variants will arrive just as scheduled, as East Asia partners are already receiving parts and items for mass production.

The new set of Macbook Air 12-inch will carry a Retina display and Intel's Broadwell processor.

Intel also cleared the air and confirmed that they will be shipping Broadwell chips to partners including Apple:

"We said we would have products on shelves for the holiday season and we continue to work with our partners and we're on schedule to have product on shelf in the holiday," Brian Krzanich said.

Digitimes also reported that this model will fill in the gap between the current ensemble, and mass production will be triggered by third quarter of 2014.

Knowing Apple, consumers should not expect a major redesign, but changes are likely to take place within the internal infrastructure.

The Macbook Air 12-inch with Retina display is predicted to sport the following specs: 2K screen resolution, 1.35 kilograms, 128GB to 256GB SSD, 1.4GHz Intel Core i5, 4GB RAM, 2x USB 3.0 ports, Mini DisplayPort or Thunderbolt 2.0, Memory card reader, and 720p FaceTime camera.

The Cupertino-based tech giant already made significant enhancements on its Macbook Air lineup a few months ago, and dropped selling price by $100.

With this development, Apple's laptop shipment is expected to increase by 15% as the newest model hit the shelves early next year, despite the existing stiff market competition.

Microsoft took on the Macbook Air directly this year, when the company released its next generation Surface Pro 3 and offered $650 store credit to trade in their lightweight Apple device for a Surface Pro 3.

However, the strategy to lure in the cult-like fanbase of Apple did not pan out well for Microsoft.
