Sony surprised us on Monday by quietly revealing the Xperia Z4 in Japan with no set plans for an international launch, but one report claims the company could have an even bigger announcement coming in May.

According to the Japanese giant is already prepping another device for late next month. One source tells the Russian site that Sony’s next phone could actually be called the Z3+, which doesn’t really suggest a new flagship phone. Otherwise we don’t know much about the alleged handset, though it could offer similar specs to the Xperia Z4.

Sony’s newest smartphone packs a 5.2-inch 1080p display, a Snapdragon 810 processor, a 2930mAh battery, 32GB of storage with microSD support, 3GB of RAM, a 20.7-megapixel rear camera and a 5-megapixel front-facing shooter. Overall that’s a pretty sweet setup, though we wouldn’t mind a Quad HD display or a bigger battery in another flagship.

As for the design, the Xperia Z4 didn’t do much to change the industrial look of its recent predecessors. It’s the same basic glass and metal we’ve seen before with a few small tweaks. We’d love to see Sony try out some of the more futuristic concepts revealed last week (pictured above).

Really though, we just want a new global Xperia smartphone. We’re not ready for Sony give up on mobile entirely. That’s what it seems like the company may be doing with its low key Xperia Z4 launch, but hopefully there actually is another flagship phone just around the corner.
