There's probably going to be a sequel. To the tenth Tony Hawk game*.
Asked what else was happening at the company aside from development of the first Ride, Tsui said that "Obviously, we're very focused on getting this done, but being the creative types that we are, we're always writing up new game proposals and things we want to do." One of the new game proposals, of course, is Ride 2. "It's just a matter of timing," he said. "With Tony Hawk: Ride finishing up [we have to think about] the sequel to the game and where that fits into our schedules. It's a lot of juggling at this point."
Of course, while Robomodo has just started thinking about the sequel, it's been an absolute certainty at Activision since, say, 1999, as have annual Tony Hawk sequels from now until they outnumber humans.
*Not counting ports, handheld versions, or spinoffs like Tony Hawk's Motion.
