If you are still in doubt about the existence of a Sony-made phablet, this next set of leaks about it should dispel your worries. After the rumored specs were confirmed by screenshots taken from a system info app, now the interface snaps above have appeared, allegedly from the 6"+ Sony Xperia ZU handset.
If the leak is legit, it indicates a giant screen size indeed, as there is a fifth column of app icons in the main menu, and six dock icons on the homescreen. This, along with the tablet-y interface come to show that we might be indeed looking at a Sony phablet of sorts, with a stylus to boot.
The-one-that-holds-kittens is speculated for unveiling June 25 in Europe, but the source says "It's gigantic, you can forget about one-handed operation with this thing," which is definitely something that can be said about phones in the screen realm of the Galaxy Mega 6.3 or the Huawei Ascend Mate.
