Oh shit. LOL. Ill play it tonight.
[edit] Here are the changes: no new characters etc. LOL 
It will automatically download the next time you boot up the game. Below is a quick rundown of what the patch entails:
①Specification changes for data interchange processing during online battles.
■PROBLEM
Since specifications in this game place the most importance in the response to controller key inputs, the player may experience temporary lag.
Slowing operations such as game animation if delays in data reception occur during data interchange in online battles when online connections are less than optimal.
■ DESCRIPTION OF CHANGES
Changes to stand-by times leading up to data reception have been made.
Further, delay times for data transmission in various environments available to online players have been tallied, and specifications added to dynamically alter stand-by times for data exchange to accommodate the slowest environments.
■ RESULTS
Screen slowdowns have been eliminated, allowing for smoother game play.
And thanks to the adjustable stand-by times, it’s possible to provide an enjoyable game environment corresponding to the online connection since gaps in data exchange in optimum environments have been reduced to a minimum.
②Changes to the antenna icon during online battles
■ PROBLEM
During online battles based on a combination of special environments, the blue icon appears regardless of the baud rate and discrepancies may occur with the actual online environment.
■ DETAILS OF CHANGES
The system has been modified to show icons corresponding to the environment reflecting the example given above.
■ RESULTS
Based on the antenna icon display that reflects actual online conditions, the quality of the connection is accurately related to the player to eliminate discrepancies in game action and the display of online conditions.
This makes it possible to accurately grasp online conditions with online battle opponents.
③Operations with chat restrictions
■ PROBLEM
Since the chat function is essential for online matches, users with chat capability restrictions were unable to make the most of the game’s online functions.
■ DETAILS OF CHANGES
When players with chat restrictions enter online rooms, specifications have been altered to disable the exchange of text and audio messages even when they are sent by other players.
Texting and voice chat capabilities can be conducted normally, however, among players with unrestricted chat capabilities.
■ RESULTS
Even if chatting is restricted, players can still take full advantage of other online functions without having to use the chat function to play online battles.
Consequently, a broader spectrum of players can enjoy KOF XII’s online play.
