The final pieces of the next Nexus puzzle are falling into place. With two new Nexus devices expected to be unveiled on 29 September, we've now seen leaked packaging designs leak. 

These box designs - secured by Android Police - are reminiscent of previous Nexus device boxes. They appear to be simple white packaging with the details on the sleeve over the top. 

The most important aspect of these is the names. We'd previously seen a rumour suggesting the new purebred Android devices would be called the Nexus 5X and Nexus 6P and that's reflected in this packaging. 

The background appears to be a satellite photo of a coastline, which is a theme of the wallpapers in Android 6.0 Marshmallow, expected to debut on these handsets. The bold use of contrasting white space and coloured blocky pieces of lettering is a nod to material design. 

Other details include a tiny illustration to match the designs we've previously seen for each of the two new Nexus handsets, as well as stating that these are 32GB models. 

We're still not entirely certain why these devices have the names they do. The 5 and 6, obviously, refer to the positions they occupy in relation to the devices they replace - the Nexus 5 and Nexus 6 of previous years - with a 5.2 and 5.7-inch displays expected respectively on these new phones.

One thought is that the P could be a tongue-in-cheek reference to phablet, or a nod to Huawei's own flagship device the P8.

There's only a week to wait, however, and Pocket-lint will be bringing you all the details from the Nexus 5X and Nexus 6P launch as it happens.
