I dont think we will see #7 until the orders and inventory for #6 are finished. I'm guessing they will want to get a significant number of #7 built before release like they did with GnR.
The reveal could have an animated Pat Lawlor, Tom Hanks (Woody) and Tim Allen (Buzz Lightyear) discovering the game and playing it... Or -- maybe they are trapped in the game... Now that might be cool.
