Upcoming Laptop features

I want to buy a laptop sometime within the next year, but I didn't want to buy it right before new features (ie. new processors, new video cards) came out because the prices prior to the new releases probably would drop. Does anybody know what new laptop hardware features are expected to be released within the next year, and when would be the best time to buy the laptop so I can minimize the cost and maximize the quality of the laptop I'm buying?
