Toyota's previously reported group-wide global sales forecast cut has gotten bigger. The company now estimates sales will fall by 350,000 additional units, for a 2008 worldwide estimated total of 9.5 million vehicles. More significantly, Toyota brand sales in the U.S. are now expected to drop 7% from 2007; this, despite reports just a month ago that sales would be flat for 2008. So this means GM will retain its title as world's largest automaker, right? Well, not exactly.
