Okay, I finally HAVE to say it. Soulcalibur V's math is WAY OFF.
Soul Blade took place in 1584 A.D., correct? Then SoulCalibur takes place three years later, then SC II and up four years later, making it 1591 A.D.
Taking place 17 years later (may I mention 1591 is the year Natsu was born) the math adds up to 1608 A.D., not 1607. =_=
So... Unless we got all the birthdates wrong (which I highly doubt) or everyone is just a year younger (which is another thing I doubt) then SCV properly takes place in 1608 A.D.
