[Quick Update]: As it turns out, this teaser site is actually just a promotional advertisement for Media Molecule's LittleBigPlanet 2 in Japan. There are hidden images of Sackboy himself and the LittleBigPlanet 2 logo in the file. Also as NoobFeed member nerdboy pointed out, the man is knitting a Sackboy. Mystery solved.
(Thanks to Siliconera for the details)
[Original Article]: Of all the ambiguous game teasers we’ve encountered all year, this one takes the cake. Sony has just revealed a teaser site for a new game. It shows an animated image of a man dressed in a nice suit, sitting menacingly in a dim lit room and…knitting. There are also two mysterious gentlemen in the background (probably his bodyguards) accompanying the knitting man.

So, um...knitting?
In case you’re wondering if this is a joke, it’s not. Additionally, the teaser site is called amimono, which is Japanese for…you guessed it: knitting. No further details were given regarding this mysterious Sony title.
Okay, so maybe the dark tone the image seems to be aiming for might not indicate a knitting game of some kind. So if not, then what is it? Does this man kill his foes with his…knitting? Is it a metaphor relating real life to…knitting? We’ll never know what this game truly is until Wednesday comes around. So if you’re interested, stay tuned for the unveiling until then.
