Yes! YES! YEEES!! This is the game i've been waiting for. Although it was code named Tenchu 360, I hope it makes its way to the PS3 as well.
Glad to see Rikkimaru's in this one, he was missed in 'Fatal Shadows'. I agree with you FCX, it doesn't really look much better than the Xbox version of 'Wrath of Heaven'. They look like they've added some new lighting and shadows and a couple of gameplay features, but nothing really 'next-gen'.
