Well, they’re hinting at something since they e-mailed us this image of Ryu Hayabusa and Ayane encircled by a purple flame.
Our guess is a Ninja Gaiden Sigma themed pinball table. Zen Studios made a Super Street Fighter II pinball table last year to coincide with the launch of Super Street Fighter II HD Remix. Ninja Gaiden Sigma 2 just came out and that Z looks a lot like the Z in their Zen Pinball logo.
The secret will be revealed on the PlayStation Blog tomorrow so the surprise sounds limited to PS3 and PSP owners.
Update: Yeah, we got this one ahead of time. A Ninja Gaiden Sigma 2 themed pinball table will arrive on PSN later this month.
