I know there have been some hints about Shenmue HD and I'm hope I'm wrong but, I don't see Shenmue HD appearing in this E3, because of Sega. So many dissapoinments years ago that I don't trust sega anymore, besides, with the Shenmue3's delay in case of announce Shenmue HD I think they would announce it next year near Shenmue 3 launch.
I hope I'm wrong!
