PAK FA T-50 (Russian Stealth)?

What will its NATO reporting name b? Even though many aviation fans r praying 4 FIRE-FOX. I don't think NATO will pick dat since USSR/Russian jets have 2 syllable code names while Firefox is 3. Watch them pic another stupid name like something like fur-tree, fish-head, fox-food, finger, floppy, flapper, fisher, flash-song or may b flash-dance.
