It’s the first day of Mobile World Congress 2014 and already we’ve got more than our fair share of awesome. Already we’ve seen Nokia pee in their pants by announcing their Nokia X phones, played with Sony’s new Z2 phone and tablet, and gotten hands-on the all-new LG G Pro 2. But in a few hours the most anticipated attraction of the event occurs: the Samsung Press Conference.

Samsung has already outed their Galaxy Gear 2 and Galaxy Gear Neo smartwatches and their “to the 5th power” promo campaign all but ensures the announcement of the Samsung Galaxy S5 . But if a recent USPTO filing has any teeth, we could also see the announcement of the Samsung Z.

What could the Samsung Z be?

The trademark description places it firmly in the mobile phone category, but we find it incredibly odd that the name doesn’t adorn the “Galaxy” branding. One would either expect the trademark to either include “Galaxy Z” or merely “Z”, leaving Samsung the option of squeezing the Z before it.

Trademarking it as the “Samsung Z” suggests that it’s not a Galaxy device at all, but if it’s a Samsung mobile phone and isn’t a Galaxy, what is it?

The end of the description tacks on a few other possibilities including tablets, TVs, audio equipment, surround sound, set top boxes, DVD players, light displays, monitors, eye glasses, computers, printers, and semi-conductors. Still we can’t help but think the Samsung Z is mobile oriented, or at the very least, an extension of their line of laptops and possibly even a new line of Chromebooks.

One possible answer? The Z could be Samsung’s long awaited Tizen phone, launching along their now Tizen-based Galaxy Gear smartwatch.

We’re not sure what the Samusng Z is or if Samsung will announce it at Mobile World Congress 2014, but we’ve only got a few hours until we find out. Phandroid will be reporting live from Samsung’s Press Conference, so stay tuned for more.

Let us know what you think the Samsung Z is – or what you hope it is – in the comments!
