Ohohoh this is gonna' be gorgeous. Click to embiggen.
I enjoyed Ultimate Ninja Storm and its sequel on the PS3 - they were fun little diversions, but most of all they were unbelievably gorgeous, with combat sequences and animation that put TV or film animation to shame.
I'm not the biggest Naruto fan - or a Naruto fan at all, in fact - but I am a fan of gorgeous, and given what CyberConnect2 pulled off on the PS3, I don't think I'll be able to ignore their first game on the PS4.
Should drop in mid/late 2015.
