Look, we're not going to beat around the bush here, this post is total wild rumor-mongering, but SE asked us to guess so we are. Sony Ericsson (Netherlands) has put up a Tweet teasing a big announcement next week, presumably at CES:
"We're getting ready for some very interesting news next week...what do you think it could be?"
Normally we'd pass this off as "just another Android announcement" and it could very well be. However and perhaps it is just coincidence but we seem to have caught a theme of tiles throughout the above picture which was posted in conjunction with the aforementioned statement.
