"We've received a PlayStation Vita system and are thinking about it," said team lead Yosuke Hayashi in a recent PlayStation Q&A. "Having said that, right now we're focused on Ninja Gaiden 3 for PS3, and after that's complete we'll start to look at ideas such as bringing out Ninja Gaiden on PS Vita because of course we'd like to expand the series."
Alright, let's toss in another concept tinged with "of course." Beyond the Wii U port (and planned 3DS game), Team Ninja will need some way to sell at least one more iteration of its latest Ninja Gaiden game. A Vita port mashed up with a Greek letter seems like a solid alpha bet.
