Well look what the cat dragged in. A Nexus 7 with Android 4.3 onboard just showed up at the Bluetooth Special Interest Group (SIG) website. This means it was just certified. Actually it was certified on May 27th, but what is unusual is the model number. It shows as ME307T, which is the same model number as the original Nexus 7. We all know that a new and improved Nexus 7 is on the way, but I would think that it would have a different model number. As to the version of Android, you will notice the Software Version Number is JWR11, which is assumed to be Android 4.3.
I am not a Bluetooth certification expert, but I highly doubt ASUS would need to re-certify the original Nexus 7 for just Android 4.3, so there has to be newer hardware. Since this information is actually available on the Bluetooth SIG website, we know it can’t be fake. Whatever it is, it’s just one more piece of evidence that we are going to see a new Nexus 7 very soon.
