This "news" was just created by Sony fandrones because VGChartz shows clearly how Sony is losing this generation on both fronts.
Which is good for the industry. Any type of industry doesnn't need the same company leading for three times in a row.
The Xbox 360 version seems like it's slightly better. It has faster load times and probably run better. And I also prefer the addition of Yoda more than Darth Vader since it's a more unique character, short and with different moves compared to the regular characters, while Darth Vader is a normal size character with a fighting style that is more similar to the other characters of Soul Calibur.
Obviously Xbox 360 has the winning hand on this one.
The most arrogant company ever. I'm glad they are last this generation. They needed that big piece of humble pie.
Nintendo won.
