"America's most influential analysts are putting paying subscribers for EA's Star Wars: The Old Republic at 1.3 million, and a conversion rate of 75 to 80 per cent.
Doug Creutz from Cowen estimated the figure of paying players to be between 1.3 million and 1.5 million, with 200,000 to 400,000 still enjoying their first month's free trial.
Baird Equity Research concurred with the 1.3 million estimate, despite originally predicting the number to be 1 million.
"More important from this point will be the trend in paid subscription levels, which will depend on user engagement and the pace of new content deployment," said analyst Sebastian Colin.
But Wedbush's Michael Pachter was more conservative, putting the figure at between 900,000 and 1.2 million.
"The worst case is that 900,000 out of 1.2 million purchasers through December 31 converted to paying subs (75%); the best case is that 1.2 million out of 1.5 million purchasers through December 31 converted (80%).""
