Speculation is part of the fun of teaser videos, but Samsung’s latest clip for its soon-to-come Galaxy S4 seemed too vague, even for a teaser.

The protagonist, Jeremy, is a little boy-slash-secret messenger solicited with the major assignment of safeguarding the next Galaxy model until its big release scheduled for March 14 in New York City.

And that’s basically the entire storyline. To elaborate for those who haven’t watched the 80-second video, Jeremy rides a limo to a posh office where he meets an executive-type figure who hands him Samsung’s “unpacked” box, presumably carrying the Galaxy S4.

Both exult over what’s inside, then Jeremy rushes back to his surprisingly modest home ― considering the big job he’s been given ― with the box in hand, vowing to guard it.

One fun detail of the teaser was the license plate on the limo-PZY 950Z-which seems to be a take on Psy, the Korean singer who went global last year.

As many are guessing, Samsung didn’t want to release a whole lot of detail on its next phone.

Rumors have been swilling around for months now, and some say that the Galaxy S4 will include eye-tracking software for scrolling through content, as according to a report from The New York Times.

The technology is said to be capable of sensing eye movements and scrolling the display of the device according to these movements.

Last month, Samsung Electronics filed a trademark for the technology by the name of “Samsung Eye Scroll.”

The Galaxy S3 also featured face and eye-tracking technology, with the screen remaining bright when the camera sensed that eyes were watching it.

Other specs for the S4 that the market is speculating on include the eight-core Exynos 5 Octa processor, a Super AMOLED HD screen and a 13 megapixel camera. Powering the new Galaxy phone will be the Android 4.2 Jelly Bean operating system, according to sources.
