Sony Xperia Z4 (or Z3 Neo) could be unveiled on April 20

So far Sony hasn't announced a top of the line smartphone in 2015, in stark contrast to what happened over the last few years. However, we may now be pretty close to a new Xperia Z series handset getting official. On the other hand, there's growing controversy over what this phone will be called.

According to a report from Japan, Sony is set to unveil a new device on April 20. That's next Monday. The company hasn't explicitly said what it will announce on that occasion, so the assumption that this is the new flagship is for now just that - an assumption. Then again, many weeks have now passed since Sony's competitors (such as Samsung and HTC) have made their latest flagships official, so perhaps the Japanese company is finally ready to follow suit.

While you might assume that the next top of the line Sony device will be called Xperia Z4, as has been extensively leaked before, you could be wrong. We've already covered a report saying we'll actually be seeing an Xperia Z3 Neo, and this has been 'confirmed' by a Twitter account specializing in leaking such stuff.

Things are still up in the air, though, because many other sources have referred to the handset as the Xperia Z4. As for what actually makes sense, the smartphone shouldn't be very different from the Xperia Z3, its predecessor, so perhaps not calling it Z4 may be realistic. Sony has been rumored to do away with launching two flagships each year, but if this Xperia Z3 Neo is succeeded by a Z4 in the fall then that clearly won't happen.
