Wi-Fi-only Xperia Z Ultra pops up at AnTuTu and FCC, could it become Sony's first tiny tablet?

A Wi-Fi-only model of Sony's first phablet, the Xperia Z Ultra, is in store, judging from its appearance in the AnTuTu benchmark and FCC certification databases. Could it be that Sony will enter the fight in the small tablets arena with the 6.4" Z Ultra, stripped of the baseband modem? 

After all, its screen diagonal is not much smaller than the one on the Nexus 7, and it has many other virtues to show for it, like being one of the thinnest phones out there, which would translate to being the thinnest tablet, at 6.5 mm. 

It is also waterproof, and can be scribbled on with a regular pencil, and so on. We don't know yet Sony's intentions with the Wi-Fi-only Xperia Z Ultra, but surely hope it will be much cheaper than its LTE-laden sibling.
