Google is expected to announce two new HTC-manufactured smartphones, allegedly called the Pixel and Pixel XL, early next month. We’ve already heard a lot about the devices thanks to countless rumors, but a fresh leak may provide even more details on one key feature: the cameras.

According to Twitter tipster LlabTooFeR, who seems to have some well-placed sources at HTC, the flagship Pixel XL (codenamed Marlin) will sport Sony camera sensors in front and back. The front-facing shooter is an older 8-megapixel IMX179 that we’ve seen before, including as the primary camera in the Nexus 5. Not bad for a selfie cam.

As for the Pixel XL’s primary camera, it’s apparently the unannounced 12-megapixel IMX378. That could represent a small upgrade over the IMX377 included in last year’s Nexus 5X and Nexus 6P, but it’s unclear if it will make much of a difference.

There’s also no mention of whether the smaller Pixel phone (codenamed Sailfish) will offer the same cameras. Earlier reports suggest the only difference between the two phones will be screen size, display resolution and battery. So hopefully that means the Pixel will offer the same high-end cameras as the Pixel XL.

Google is expected to unveil both phones at an event on October 4 along with the first Daydream VR headset, a new Chromecast and Google Home. LlabTooFeR also promises to share more information “later,” so we should learn even more about the Pixel and Pixel XL before the big announcement next month.
