These transformative games include five exclusive titles for Kinect for Xbox 360, the controller-free system introduced for Xbox 360 this November. Look for these games to hit stores in early 2011.

Google Inc. (NASDAQ:GOOG)

Google, Inc. (NASDAQ:GOOG) Ventures, the search giant’s venture capital arm, has hired the man behind Google (NASDAQ:GOOG) Voice to build a new start-up. The creator of Google Voice, Craig Walker, will become a sort of in-house entrepreneur for Google (NASDAQ:GOOG), through Google’s venture capital arm, Google Ventures.

So what is the venture that Walker is working on? The New York Times asked the same question, but Walker would only speak in vague terms about what it will be – so we all have to stay tuned.

Citigroup Inc. (NYSE:C)

Citigroup (NYSE:C) and other dealers in financial ‘swaps’ may soon be regulated by the CFTC. Citigroup (NYSE:C) is one of the major swaps dealers that could come under regulation by the Commodities Futures Trading Commission (CFTC), according to commission Chairman Gary Gensler.

The news was announced at a swaps industry conference in New York City on Tuesday, and could mean Citigroup (NYSE:C) will have to stay on its toes as a swaps dealer.

There will probably be more movement when trading continues for Microsoft Corp. (NASDAQ:MSFT), Google Inc. (NASDAQ:GOOG) and Citigroup Inc. (NYSE:C).
