The title of LG's teaser video includes the name "LG Premiere," which could be the name of the forthcoming flagship — albeit that would be confusingly similar to the mid-tier LG Premier of yore. So, hopefully the company is going to make that last 'e' really count.
Rather, we're betting on some sort of Leap Motion -style gesture control interface being added to the front of the handset, using sensors to detect a hovering hand, for example — probably accompanied by heavy marketing about how filthy-with-germs phone screens are so it's totally better you don't actually touch them.
We just hope that another detail in LG's description for the teaser video, in which it asks its followers whether they're "prepared to get stunned by the LG Premiere," does not augur a highly potent new form of contactless haptic feedback.
