Sony has scheduled an event to allow us to "See the future" of PlayStation on February 20th in New York. Investors as well as media outlets have been invited to the event, and together with the following teaser video, it seems that a PlayStation 4 announcement is coming very soon.
Specifications of the device have already been leaked on the internet, although it's unknown how accurate any of these reports were. It's also unlikely that we will get any confirmation of the accuracy of these rumors at the event, but Sony will show off the power of the device by showing some games if a PS4 announcement is on the cards.
I can safely say that I am more excited right now than I've been for a long time for the gaming industry, and can't wait to see what Sony has to offer.
