Keep on changin' and Keep on Trekkin' for the next 50 years. Reboot/Re-Imagine/Retcon/Remake etc just stay relevant and stay cool. Trek will have to change a great deal in the next decade to keep up with the technological revolution currently taking place (cheap computing devices/smart devices/phones/tablets/smart tv/internet/robotics/medicine).. these movies are just the start. For every old fan that gets pissed off there should be 10 new ones to take their place. Thats how you keep it going.
