Eurogamer reports that Rez HD could appear on Xbox Live Arcade within days.
"The game is being prepped and it's just waiting for the green light," said the spokesperson. "Maybe next week?" Cough wink nudge.
Rez HD is a remake of Dreamcast and PS2 title Rez. You shoot things in time to music in wacky environments, like some kind of Jean Michel-Jarre of the Future.
The game will cost 800 Points (GBP 6.80 / EUR 9.30) when it does arrive, and you can read what we thought of it in our recent Rez HD first impressions.
