Ninja Theory's website has a video giving an overview of their studio and it includes footage from an unknown, potentially upcoming Ninja Theory project:

Can we just agree that Ninja Theory is the best company name ever, it sounds it could be an awesome subject at school!

I have a major in business, and a minor in ninja theory.

@nakattack: Sounds awesome, you're hired!

Ninja please, back in my day you learned Ninja Theory on the job, where death was an occupational hazard! Now every snot-nosed brat out of school thinks they can become Hattori Hanzo just because they got a piece of paper calling themselves Ninja Theory masters.

GO HIDE UNDER A POND WITH A BAMBOO STRAW OLD MAN

Stringer: That's good. That's like a forty degree day. Ain't nobody got nuttin to say about a forty degree day. Fifty? Bring a smile to your face. Sixty? Shit, ninjas are damn near barbecuing that mothafucka. Go down to twenty? Ninjas get they bitch on. Get they blood complainin... but forty? Nobody give a FUCK about forty. Nobody remember forty, and ya'll ninjas is giving me way too many forty degree days. What the fuck?!

something something samurai studies

YEAH.

I'm surprise Ninja Theory still hasn't made a game about Ninja's yet. Anyway I've seen the glimpses of the new game in the vid, and I can't really give an opinion of it yet...

Maybe I will! And while I sneak into the evil daimyo's castle to take his head you can explain to your mother why you're still hanging around the house instead of finding a nice girl to continue the bloodline!

Young ninjas these days got no respect for their elders.

Ninja please, I ain't got no respect for you because you fart and call it a smoke bomb.

Since Devil May Cry, I'll buy whatever the fuck Ninja Theory want me to.

She looks overly dollish and made of clay in some of those screenshots. I'm still excited about the game though, since I loved Enslaved and DMC. HS did nothing for me, but a sequel eventually would be cool.

DMC was a real leap forward for them in terms of gameplay. Enslaved had an interesting story but really simplistic combat and traversal. Glad to see the studio evolving, as a big fan of the new DMC I'm looking forward to their next project. Hope they can keep the same momentum.

I just wish they would go ahead and get started on DmC2. I'd really like to see where they would take the series, especially with the Dante vs. Vergil stuff.

They haven't made a bad game yet, so I'm interested to see what this ends up being. I have to wonder if this means Capcom isn't trusting them with a DMC 2 after the sales of the first one. Or perhaps they are a 2 game team now, hard to imagine with the mediocrity of their sales, but I did see they were hiring.
