With the recent announcements of the PadFone Infinity, the MeMo Pad 8 and 10 and of course that Google darling Nexus 7, you would be forgiven if you thought ASUS was done with tablets for the year. That appears to be far from the truth, however, as this recent FCC filing shows a mystery ASUS tablet that we've not heard about before. The TF502T model number is in line with other Transformer slates, so we're suspecting this to be an upcoming Transformer Pad. There's not much else to glean from the documents, but we do see that it carries 802.11n WiFi, Bluetooth and NFC at the very least. While we wait to hear more details about this, feel free to hit the source if you fancy a look at FCC minutiae.
