I agree that Capper was brought in to set the company up for sale; however no sale will happen until they settle the huge potential lawsuit outstanding as that is a poison pill to any potential acquiror.
Keep an eye out for settlement of the suit and if terms are at all favorable that will be the time to buy the stock. Till then it is dead money since they are stalled.
C3 was existing product. C5 I beleive is the name of the next generation product coming out in 2011. Cheaper, Faster, Better (& stronger - more features). Like the $6m Dollar Man if you are old enough to remember the show from the 70's..
