According to a poll conducted by Nielsen, the most eagerly anticipated games for 2012 are Halo 4 and Assassin's Creed 3. If you asked me this question, I'd say BioShock Infinite and Max Payne 3, so apparently I'm pretty average.
The "anticipation level" among gaming consumers was derived from combining eight key consumer metrics, including Awareness and Purchase Interest, into one overall score. That score was then compared to scores from all previous games released on the same platform, to determine the percentile ranking of the upcoming title. Some of these games will get release dates and more info at E3 2012.
