Apple has announced on Monday that the company is set to beat last year's opening weekend sales record of 10 million units sold. According to the company, pre-orders for the new flagship units, the iPhone 6s and iPhone 6s Plus, have so far been "very strong around the world."

"We are on pace to beat last year's 10 million unit first-weekend record when the new iPhones go on sale September 25," a spokesperson for Apple said, according to Mashable.

"As many customers noticed, the online demand for iPhone 6s Plus has been exceptionally strong and exceeded our own forecasts for the pre-order period. We are working to catch up as quickly as we can," the spokesperson added. 

The pre-order figures of Apple's flagship phones have been steadily on the rise, with the pre-orders for its iPhone 5 in 2012 reaching 2 million in just 24 hours. Last year, the company was able to sell 4 million iPhone 6 and iPhone 6 Plus units within the first 24 hours of pre-order sales, reports CNN Money.

The company, however, has not given the exact figures for the pre-orders of the iPhone 6s and iPhone 6s Plus, triggering speculation. People have become even more curious due to the fact that China, which is not among the pre-order markets last year, is included in this year's markets.

China has recently become a vital country for Apple, accounting for nearly 27 percent of its overall sales in its most recent quarter.

The brand new iPhone models are practically the same in appearance as the previous year's flagships. However, the newer models boast better processing power, a stronger frame, and a number of new features such as 3D Touch. It is also offered in a new color, Rose Gold.
