Looks like gamers waiting for PS4 will be getting the big announcement from Sony sooner rather than later as February 20th looks to be the big announcement.
Sony's social networks lit up earlier posting a message with "see the future" with an accompanying link: https://us.playstation.com/meeting2013/.
At the link, users can sign-up with their e-mail address for the first to be notified, with the above image listing a February 20th announce date with the following video displayed as well.
There have been a number of rumors regarding the PS4 which includes dropping the DualShock Controller to keeping it again, to biometric capabilities, to even going to more of an all digital route eliminating the use of hard copies of games.
In addition to the PS4, it's also a given that Microsoft will be launching their next-generation console, the "XBox 720."
