It’s official. Nokia will be on hand at Mobile World Congress in Barcelona on opening day. Invites were just sent out and come February 25th at 9am, the company revealed it is holding a major press event where they will presumably reveal some new hardware and services for 2013.

Last year, Nokia shocked the crowd (and the world) by revealing the PureView 808 with a jaw-dropping 41MP camera. We were there for that event and remember the gasps from the audience. Will Nokia do this same this year but with Windows Phone? We’re confident they won’t disappoint.

Rumors have circulated that Nokia will reveal at least one new ‘flagship’ Windows Phone but possible up to a few (we still haven’t heard if there will be a Lumia 720 yet).  That flagship phone could be destined for Verizon with another large camera sensor on board. That one reportedly has the codename 'Laser'.

Likewise, AT&T may be getting one of the first phones with a new aluminum body aka 'EOS'. Another device, codenamed ‘Catwalk’, may be one of many new Lumia phones for 2013 with a new, updated design.

In addition, some more information and even a demonstration of Nokia Music+ is expected to be on hand, giving music fans something to cheer about.

Finally, let’s not forget that Nokia is also rumored to be revealing a new Windows 8 tablet of some sort. Featuring a keyboard cover with built in extended battery, not much else is known about the device—or even if it exists.

Needless to say, it should be an exciting morning.

Of course Windows Phone Central will be there to cover the event live, so make sure you bookmark us for the event.
