There's an economic concept called "pricing behind the curve" that looks a lot like "dumping". But it's different.
Pricing behind the curve means you base the price of your product on the average component cost over the life time instead of your actual current cost. Microsoft does that with the Xbox. In effect you subsidise the early models and make up for that in the long run. It's a valid strategy to gain market share quickly and does not hurt consumers.
Dumping means you subsidise your own product to push competitors out of business. It does hurt competition in the long run if done effectively. Dumping is illegal and you can get into a lot of trouble if you are found doing it.
Since the competing companies are not accusing anyone of dumping, I think it is safe to say no dumping is currently going on.
