Sony releases mysterious teaser for its next phone

Sony is apparently going to introduce something at Mobile World Congress next week, going off the fact that its Xperia account tweeted a teaser video for the annual phone event this morning. The video shows a hand and a bunch of ripples cascading down onto it from above. It also says whatever this video is hinting at will be announced on February 26th.
