Probably some more lines for SHenmue 1+2 HD
Might be a test of the waters to see if Shenmue 3 can get some sort of funding? They should do a kickstarter for Shenmue 3. I can honestly play the game with slightly better graphics then Shemue 2, after all we've been waiting all this time.
I think knowing Sega they will take the safe approach with RYo Hazuki and do the HD remakes for less expenses. If it finally returns the games to profibility then Shenmue could very well finally be a success considering the enourmous cost to produce the game around $50,000,000. Hopefully Sega releases these games and gets support from the gamers so we can finally see a Shenmue 3.
