We've known for some time that Ninja Gaiden 2 will be releasing on June the 3rd, but some of the game's finer details have been a bit under wraps. In an article in Famitsu (kindly translated by folks over at the Ninja Fortress boards and reposted at NeoGAF) there is some more details on the game's changes and tweaks. There's tons of little tidbits, but some of the biggest ones are more revealing, like the fact that some gamers have beaten the game's beta version in 15 hours (difficulty wasn't mentioned.)

Other things of note include the fact that there are no longer armlets in the game, as Ryu more or less has those abilities inherently now, and the fact hat Ryu no longer carries around potions to heal. Healing items are now different sorts of powders ("'This time, Ryu uses drugs to heal' he said while laughing."). And if you missed the xbox.com update, the Flame Wheels are now flaming birds that will circle you, attacking enemies who come too close.
