Not sure if this would be of long-term interest for the article, but just for my own interest I'd like to compile a timeline of the clues that led up to the E3 announcement. Here are a few that I heard about in the days leading up to it...
*5/25 - Yu Suzuki re-activated his Twitter account
*5/26 - YS Twitter account shows him visiting with Wu Rensi Roshi
*6/11 - YS Twitter account shows picture of Las Vegas, indicating that he is on his way to E3 in LA
*6/14 - YS Twitter account shows picture of forklift at E3
Personally I was taking this all with a grain of salt. The first thing that really made me raise my eyebrow was when someone discovered that shenmue.com had been transferred to Amazon hosting a week or two prior to E3. However, as it turns out, shenmue.com still doesn't seem to load.
Of course, such a timeline could be expanded to cover the last several years of developments.
