70-400 II - 4x AF speed improvement

Big improvement if true. I wonder if this only applies to certain bodies.

"With its new LSI drive circuit, autofocus speed of the SSM (Super Sonic Wave Motor) is around four times quicker than before. Teamed with enhanced tracking AF, the upgraded lens is now even more suitable for capturing stills and Full HD video of fast-moving subjects."
