baka si silver samurai ang kalaban nya, hahahaha
That's a given. The Silver Samurai is the half-brother of Mariko Yashida, who happens to be Wolverine's "Sawsawan in Japan."
The Japanese story arc just won't happen without Mariko. hence it won't happen without the Clan Yashida and its silver-armored leader.
Here's their problem though. X-Men 3: The Last Stand's ending "stole" the premise of Wolverine's Japanese story arc, mainly because Wolverine became the love interest of Jean Grey as Cyclops decided to fuck Lois Lane in the other movie. If they're going to repeat that ending, it would have less of an emotional impact.
Oh well...
