The iPhone 6 has leaked yet again, this time surfacing in a promotional flyer that reveals pricing details for both the 4.7- and the 5.5-inch models.

Apple's next-generation smartphone is among the most highly-anticipated devices of this year and a slew of leaks and rumors are boosting anticipation ahead of the big launch. Apple is widely expected to finally move to larger screens with its new smartphone, as the iPhone 6 will reportedly come in two models: one with a 4.7-inch screen and the other with a massive 5.5-inch display.

The latest iPhone 6 leak now comes out of China in the form of a promotional flyer and shows both models of the smartphone, complete with pricing details. The folks over at GSM Insider have spotted the flyer on a user's Weibo account. The promotional flyer is in Chinese, but you don't necessarily have to know the language to see the two models and their respective prices.

Looking at this leaked material, the 4.7-inch iPhone 6 appears on the left, sporting a CNY$5,288 (about $852) price tag, while the larger 5.5-inch model is on the right, with a CNY$6,288 (roughly $1,013) price tag.

The iPhone 6 is expected to boast notable improvements over its predecessor, boasting a larger and tougher display, faster A8 processor, enhanced 4G LTE, improved fingerprint reader, wireless charging capabilities, and perhaps even NFC.

The promotional flyer further notes a launch date of Sept. 19, which falls in line with previous rumors that claimed that Apple would unveil the iPhone 6 on Sept. 9 and the handset would go on sale on Sept. 19.

It remains unclear at this point, however, if both iPhone 6 models will launch at the same time, or the 4.7-inch variant will arrive first. Recent speculation again claimed that the 5.5-inch version, dubbed the iPhone Air, was facing some production issues that may delay its launch or result in limited availability, but nothing is confirmed.

It's all in the rumor state for now, as Apple has not offered any official details regarding its upcoming iPhone 6. As always in such cases, make sure to take all leaks, rumors and speculation with a hefty grain of salt.
