The Xperia Z4 isn’t expected to make an official appearance for a few more months, but a new rumor claims it could arrive a lot sooner than that. According to one Japanese blog, the company has a big Xperia announcement set for Monday, April 20 where the Xperia Z4 may finally get unveiled.

The news comes as a surprise, and we’d treat the whole thing with suspicion for now. Then again, at the rate the Xperia Z4 has been leaking recently Sony may not have much of a choice. A hasty unveiling could also explain why the company hasn’t sent out official invitations to the event.

We’re expecting the Xperia Z4 to pack a 5.2-inch 1080p display, a Snapdragon 810 processor, a 20-megapixel rear camera, a 4.8-megapixel front-facing shooter, 32GB of storage and 3GB of RAM. It should ship running Android 5.0.2 Lollipop out of the box.

On the design side, we’re not expecting a huge overhaul from last year’s Xperia Z3. Recent leaks suggest a similar industrial design with a few small tweaks. Most notable may be the lack of a magnetic charging port, though hopefully the Xperia Z4 is still just as water-resistant as its predecessors.

We’ll be keeping an eye out for any more Xperia news leading up to the rumored event. Even if the Xperia Z4 doesn’t make an appearance until later this year, it’s possible Sony has something else planned for April.
