And maybe next someone will also unveil a new STEALTH game Ninja [Insert Adjective] for the first time.

Don't anybody mention that travesty gone further south by Activision. Yes the one they kept remaking like a wayward Tomb Raider franchise... before they whored it off to the first bidder.

Ninja's are the most abused gameplay.

Perfect Ninja game? Climb most walls (doesn't even have to be detailed like Assassin's Creed), cross some ceilings, freely use a physics based grappling hook to hang enemies, swing from scenery and swing it around for effect.
Sword use, magic use, wonderful stealth kills, target enemies in a queue and unleash (the character can just jump between them, slashing, for all I care).

Basic elements that we've seen portrayed in many other games, but do you get a full blown Ninja game that does the Ninja honor?

....well not from Microsoft, unless you felt Shadowrun went well.
Could Activision please stop publishing sloppy games? Control should always feel tight, like a good reaction should. For ideas on what I mean, please play a Capcom title. There is no easing in their action animations.
Snappy. Tight. Stealth. Ninja.

I'm highly anticipating this game to see once again another Ninja Gaiden wanna-be fail with a more than standard combat system.

Now that Itagaki has disappeared under the radar, who will create authentic Ninja games? I'm not expecting much from the team that created the Tenchu games, as they miserably failed to improve their experience since the first in the series.

Although Microsoft making it an exclusive might provide them with a little more dev-power than they are usually accustomed to in order to make this successful.

Who knows, only time will tell...
