While official announcement have not been made yet, I guess there is no point in denying it. Yes - Dawn of Fantasy will be available both on PC and Xbox 360.
We got our inspiration from Battles for Middle Earth 2 Xbox360 port. Dawn of Fantasy uses similar interface and controls.
However the main "appeal" to Xbox market we’ll keep a secret for a week longer - until we release a lengthy 4 minute Video Trailer which will tell the whole story.
