Cautious optimism is how I'm feeling here. BUT if we look at the facts, there is a decent possibility that Shenmue could return on Sony's console.
FACT: Yu Suzuki has stated that he believes that Sega will allow him to make the game.
FACT: He said this in front of the lead architect for the PS4
FACT: Said lead architect and Yu Suzuki are good friends
FACT: Sega has mentioned in the past they would be open to leasing Shenmue for console exclusivity
FACT: Now Sony mentions this news we're reading now.
Let's keep our fingers crossed. The chances of Shenmue returning this next generation are far better than it has been in years past. It's just all up to Sega to come up off of the IP.
