Unless Activision can back up their claims, then it's no good. They dropped the game, what rights should they still have? They're just trying to get money out of a promising game. A divorced husband can't sue his ex-wife for dating a better looking man, so I think a lot of what Activision is saying is crap to stall the release.
"A few times in my life I've had moments of absolute clarity. When for a few brief seconds, the silence drowns out the noise and I can feel rather than think, and things seem so sharp and the world seems so fresh. I can never make these moments last. I cling to them, but like everything, they fade. I've lived my life on these moments. They pull me back to the present and I realize that everything is exactly the way it was meant to be."
