Pues visitando la wikipedia, he leido esto:
* Tony Hawk's Proving Ground is also set to include a demo of another Neversoft project, Guitar Hero 3: Legends of Rock, for the Xbox 360 platform only.
* The Tony Hawk's Proving Ground demo will be released in September on Xbox Live and possibly on the Playstation Network.
El mundo ficticio será 50% más grande que Tony Hawk's Project 8.
Tony hawk proving ground y guitar hero 3 tienen fecha prevista para octubre del 2007
