Polytron has announced that Fez will be released on Xbox Live Arcade next year.
"Fez is coming to Xbox Live Arcade early 2010" is the headline on the official site, which doesn't comment on the hold-up.
Fez, which won an award at the Independent Games Festival last year, always cuts a fine form in videos. It's about a 2D man who discovers the world is 3D, with various perspective-skewing implications for its puzzle-platform gameplay.
