JoBlo.com has it from an inside tip that Ronan will be the villain.
If you recall, we've already heard that Thanos, The Collector, and The Controller will be/are the villains in the movie as well.
Lee Pace was recently said to be the villain in the movie, so it's quite possible the actor could be playing one of the above, or of course, someone totally different.
Seems like a majority of the Marvel Studios rumors never pan out, though.
The Guardians of the Galaxy movie has an August 1, 2014 release directed by James Gunn and starring Chris Pratt as Peter Quill Star-Lord, Dave Bautista as Drax The Destroyer and Zoe Saldana as Gamora.
