Ninja Gaiden Sigma II On the Way with Trophies?

Yosuke Hayashi, Producer of Team Ninja did say this though:

“We are definitely willing to make trophy system available in our sequel.
In order to deliver our new NINJA GAIDEN as soon as possible , we have to continue to move forward further.”

Does that mean Ninja Gaiden Sigma II is on the way? Remeber though, this e-mail can be completely fake, thats why this is filed under rumors. You also need to consider the producer of the team actually e-mailing him back himself.
