Apple launched the iPad Air 2 and Mini 3 in a few flagship stores Wednesday, a week after accepting pre-orders for the devices, CNET reported.

The release date was not specifically stated by the Cupertino-based company during its event on Oct. 16. Apple only announced the availability for pre-orders and gave vague references to when it will finally be launched in the physical stores.

New versions are now being rolled out without a fuss in a few select cities.

The soft launch of the upcoming tablet line is said to be caused by an increasing demand for the iPhone 6 and 6 Plus models, according to an employee for Apple's Fifth Avenue branch in New York.

The source also said that people have been lining up every day for the latest iPhone model, as stocks run out every time a shipment arrives.

While CEO Tim Cook said that the production of the new iPhones is not able to meet the demands from the public, he didn't address any solution in fixing the company's inventory concerns as of the moment during Apple's earnings conference call on Monday.

The Grand Central Terminal store in Manhattan, New York, only had a few people looking at the retail displays of the new tablets.

The iPad Air 2 , which retails starting at $499, is 18 percent thinner than previous models and has an integrated A8X processor. It also has the Touch ID fingerprint sensor, which makes it the first model from the tablet line to have the security feature.

Along with the iPad Air 2, the iPad Mini 3, which retails for at least $399, was also released. While features are said to be almost similar to the previous version, the newest model also comes with the Touch ID sensor and an optional gold back case, according to V3.

Both tablets have 16GB, 64GB and 128GB versions.
