In the end, there will most likely be one suit, and it will most likely be run by the firm who has a class representative with the largest losses.
I have spoken to two very fine firms who at the moment have slightly different levels of commitment to this matter.
Tom Shapiro is seriously pondering it. His firm, Shapiro Haber & Urmy, is a succesful class action law firm with experience suing Chinese companies and major accounting firms. Their number is (617) 439-3939.
Cohen Milstein Sellers & Toll PLLC, of NYC, is a leading class action plaintiff's firm that is committed to filing a complaint. That firm is now representing the female employees of Walmart, and has previously sued Chinese companies and major accounting firms as well. The contact person there for this mater is Michael B. Eisenkraft - 212-838-0177.
If you sit back and do nothing, you will likely be included in the ultimate class action. If you want to learn about how this case is going to proceed, you can try calling one of these gentlemen. If your losses are in six figures, you have a shot at being the class representative, in which case you should certainly call one or both of them.
