Perfect time to release Shenmue 1&2 HD, with the Wii at almost 100 Million & the HD twins closing in on 80 million, they could maximise sales on all three of their "arcades" and bring it over to PC of course.
Then, with next gen just around the corner, we'll be able to see how much weight a possible Shenmue 3 would have.
Exactly between the 3 consoles that is a huge market Sega could place Shenmue in, alogn with PC for those Sega gamers who decided to go the PC route. Shenmue 3 next gen would seriously be ground breaking, I really hope Yu SUzuki continues to direct and produce the game. =)
