The mysterious user, which is by the way newbie at the forum, claims that their store has already received the 16GB models.
The photos are of very low quality but they are the only available at the moment. However, it is visible that the info says available memory of 14.4 GB and the firmware version 1.1.2. Looks real :)
According to Jimpo, the model shall be officially announced on 16th of October.
