Ninja Theory tests the water on Heavenly Sword 2

According to this, Ninja Theory has been focus testing aspects of Heavenly Sword 2 in Chicago.

"They initially asked for video game background, then they had a follow-up phone call asking which games I had played or owned, focusing heavily on Heavenly Sword," said one guy involved with the activity. "There were three surveys done on Monday, groups of six for the first two, four for the last group (my group). Predominantly males, asking about our impressions on Prince of Persia, God of War, Ninja Gaiden and, of course, Heavenly Sword. Some questions were asked about why Heavenly Sword didn't sell so well, what our impressions were on the gameplay, how the cutscenes were done, combat mechanics."

There's more through the link. It's already known a sequel to the PS3 title is in the works.
