Sony to unveil new Xperia Z4 tablet at MWC 2015

Sony just teased their Xperia Z4 tablet ahead of the Mobile World Conference 2015 on March 2nd. Sony posted this new photo of the ultra slim device to their Google+ account. The other day we clued you in on Sony's accidental leak of the new Xperia Z4 on their Xperia Lounge app. We surmised that this was ahead of a big announcement at the Mobile World Conference 2015. It looks like we were on track because Sony tagged their latest photo post to Google+ with #SonyMWC.

It looks like they will be debuting the Xperia Z4 Tablet at the MWC 2015. Sony has yet to post any information about an accompanying Z4 smartphone, so we will have to wait and see if they announce that at a later date.

Some Sony consumers are frustrated that Sony has yet to release the Android 5.0 update for its Z2 and Z3 phones before the unveiling of their next flagship device. The update was originally due to come out in February. Seeing how February is almost over, we may see the new Xperia Z4 Tablet with Lollipop before we see Android 5.0 for Sony's older devices.

Soon we won't have to guess. Slash Gear will be covering the Mobile World Congress live, bring you all the hottest news from big mobile device manufacturers.
