There may be some correlation between which is leading in search and which will sell the most. However it would be very hard to say that a big lead in search will mean a crushing defeat. Also, this might be predictive of the first year or 2 of sales , but long term through the generation I don;t think this has much predictive value.
Also HDDVD vs. Blu-ray was as do or die thing. There was only going to be one man standing at the end. And search predictions are probably better at predicting a winner take all scenario than a market share scenario.
