Tomonobu Itagaki says there's no way other developers will beat what they're doing with Ninja Gaiden 2. He goes even further saying that those devs will lose their motivation after beholding what's coming next from them.
"GI: Games like Code Cronos and Ninja Gaiden 2 have been sort of waiting in the wings for quite a while now. Do you think we'll be hearing some announcements about those titles in 2007?
Itagaki: I'd like to show everybody some of the new stuff that we've been working on in the near future. The only problem with that is that when the other developers see what we're doing, they're going to lose all of their motivation to create any game in the same genre, because there's no way they can beat it."
Big words considering the weight of the titles he's refering to, just to name a couple, Devil May Cry and God of War.
