Prospective buyers of Google's next-gen Nexus 5 (2015), expected to be unveiled on 29 September, might have a long wait before they can get their hands on the device. That is because pre-orders will open only on 13 October.

Generally, Nexus devices have been available for orders shortly after launch. But a TalkAndroid report, quoting trusted internal sources, says both the new Nexus phones, manufactured by LG and Huawei, will begin accepting orders later than usual. Orders could take anywhere between 1-3 weeks to ship.

Pricing details of the phones are still unknown. It is believed that the smartphone manufactured by LG would cost less than Huawei's handset, which sports a bigger screen.

Rumours suggest both phones will run Google's latest Android 6.0 (Marshmallow) out of the box. Other rumoured technical specs of the LG-manufactured Nexus 5 suggest a 5.2in display and a 13MP rear camera. Under the hood, the handset is rumoured to feature a Qualcomm Snapdragon 808 SoC with 3GB RAM. A fingerprint sensor and USB Type-C connector are also predicted.

Key technical specs of the Huawei-manufactured Nexus 5 are not known. But this phone will be a flagship to compete with the likes of Samsung's Galaxy S6/S6 Edge and even the more recent Galaxy S6 Edge Plus. The new Nexus devices are also expected to pose a challenge to Apple's new iPhone 6s and iPhone 6s Plus devices, to be unveiled in San Francisco on 9 September.
