The Xperia Z4 is still only slated to launch in Japan, but it looks like Sony may rebrand its new phone for the international market. A leaked internal document obtained by Xperia Blog suggests the device will launch as the Z3+ around the world.

That name makes a lot more sense, especially considering what Sony’s newest Xperia actually brings to the table. The Z4 offers a faster Snapdragon 810 processor, an improved 5-megapixel front-facing camera and an uncovered microUSB port that’s still water-resistant. Otherwise, it’s pretty much the same as last year’s Xperia Z3.

Then again, switching the name like this could mean more confusion later this year. What will Sony call its next flagship phone? Will the rumored Xperia Z4 Ultra launch as the flagship Z4 everywhere but Japan? We have no idea what Sony is thinking, but hopefully the company has at least some idea what comes next.

The best strategy may be to simply abandon the Xperia Z brand completely. It never really caught on in the U.S., and it seems pretty clear the company hasn’t had much luck overall with its Xperia lineup. It’s not too late to try a new name, and with the marketing campaign to back it up that just might work.
