It didn't start out very promisingly. Sony Computer Entertainment president Kaz Hirai delivered a keynote speech devoid of news, focusing instead on the company's current thoughts on networking and PlayStation trends in general rather than blasting us with announcements.
But a second, less-publicised Sony Japan press conference made up the difference. It also took a few people by surprise - Sony hadn't made a big deal about it, with the majority of Western journalists oblivious to it until it had started. Even Microsoft, who had planned a panel discussion on Project Natal involving Hideo Kojima, Toshihiro Nagoshi and Keiji Inafune, was caught on the hop, delaying the start of its event to give people time to attend both.
Nor did it end there. With the conference over, Sony's European PR department started firing out its own press releases, covering region-specific bundles, and a PSPgo reward programme for people who upgrade from an existing handheld, among other subjects.
With Sony making the most noise of anyone at TGS, then, we thought it only sensible to give latecomers a head-start in getting up to speed by rounding up all the pertinent stories and some of the more exciting videos in one place: this page. We do so at great personal risk of being flamed for giving them preferential treatment, of course, but do so anyway in the belief that the majority will accept it's useful to have it all in one place, and that it's not the sign of a secret blood oath involving a serrated DualShock and a naked Emotion Engine or anything like that. (We're saving that for the Expo).
