Instead of creating another thread, how do you think Sega did at E3? I personally think it was a mixed bag. Although I think they had a wide range of games, none of it seemed to hit the media as strongly as most of them already have a set market. Warhammer already has it's fans and so does Yakuza and even Sonic. Think they missing that big spark like Alien Isolation or something that draws attention to them.
I hinted at this before, but I wonder if a little show like they used to do on youtube would help to push all of Sega's content in one place. They don't need people talking etc, but have a small Sega intro and go straight into the trailers and gameplay. They could even say that game x is available to play at E3 and so on.
