If Sony does indeed introduce its Xperia Z4 at Mobile World Congress in March, it won’t be the only phone in the company’s new arsenal. Xperia Blog points us toward some new renders of an Xperia E4, which we can only assume is the follow-up to Sony’s E3 from last year. You want affordable? That was the E3’s game, and I’m guessing the E4 will carry on that trend.

It’s always difficult to get a real feel for a device that’s wrapped up in a case, but the new renders still give us a pretty good look at what to expect. There are some inconsistencies with the renders that have been provided, however, so don’t write this one down in ink just yet. The above flip case render isn’t anything all that special—side buttons, Sony logo, speakers, front-facing camera. Typical Xperia design.

The second render has more chamfered edges, and no Sony logo is present. There’s also a small volume/rotation lock toggle; it looks more like an iPhone 3G than anything. But that’s neither here or there. The side power button is patented Sony, so there’s no mistaking this device as an Xperia variation.

Rumored specs for the Xperia E4 include a 5-inch qHD (540 x 960) display, 1.3GHz quad-core processor, 1GB of RAM, 8GB of internal storage and a 5-megapixel rear-facing camera. Xperia Blog says these specs have “broadly been confirmed,” pointing to a retail listing by for a device named Xperia E1 II, which is apparently a code name for the E4.

The Xperia Z4 will be Sony’s next exciting flagship, but it sounds like there will be something for everybody. We should learn more at next month’s big mobile-focused show in Barcelona.
