Lets try to get another developer interested in buying the rights to Shenmue... but judgeing off of games from companies I've played I'd say Namco Tales Studio or Tri-Ace are the only ones that could do the series justice!
I'd say the series selling is very likely instead of not likely thanks to the fact the sales were decreased by Sega's stupidity with the "multi-platform" approach that led each console to get a tiny bit of what Sega was... If Shenmue 1 and 2 were available for PS2 and GC as well as the Xbox I think we probably would have seen a 3 already. (This way they could have identified which platform the series was strong on and went from there...)
Hell if it goes to NTS they could call it Tales of Shenmue
