Players of the console and arcade versions of SSFIV: AE have been able to enjoy the 2012 patch for some time now--since late 2011, in fact. The PC version of the update, which addresses some previous balancing issues, has taken a little longer to get out the door, but it's finally almost here. Check out this message from the [edit]US producer, Derek Neal[/edit]:
"I’ve got some good news to share with everyone! As of today, development on the PC version of the 2012 update has been almost completed. All that’s left are a couple of final tweaks, which we should knock out in the next couple of days. As a result, we are currently on the verge of being able to submit it to Microsoft, which is basically the last step in the development process. Our current target date is 2/28/2012.
So everyone, please cross your fingers and wish us good luck! If everything goes smoothly in submission, you should be seeing this update go live soon."
You heard the man--keep those fingers crossed!
