Looks like Sony Ericsson will be announcing some new mobile hardware at CES in Las Vegas after all. Engadget spotted a poster of a very slim phone that bears more than a resemblance to the ANZU (Xperia X12). The poster doesn’t reveal much, although it does show what appears to be a 3.5mm jack on the side. It has the tagline, “Believe in More Entertainment at the Touch of a Button”. We will no doubt finally hear some official news on this in the next day or two.
