That estimate is much lower than the 14.4 million households that Adams Media Research said in June would be playing Blu-rays by the end of the year. But if it is to come true, about 1 million more standalone players and 2.3 million more PS3s must be sold through the holidays.
Prices have dropped in recent months, and Blu-ray players can be found online for less than $200, encouraging hope for adoption of the format.
"The only dark cloud is the economy," David Bishop, president of Sony Pictures Home Entertainment, told a panel. He said the consumer products side of Sony Corp. is "showing no slowdown in the adoption of the PlayStation 3."
There are 5.7 million PS3s installed in the United States now, and Sony and expects to sell 4 million to 5 million more by March.
"We remain pretty confident that we'll meet our targets for the fiscal year," said Julie Han, spokeswoman for Sony Computer Entertainment America.
These so-called "early adopters" of video technology are especially important because they tend to buy more movies than consumers who join a trend later.
"These are the heavy buyers, the heavy collectors," said Craig Kornblau, president of Universal Studios Home Entertainment.
Executives agreed it is still the early days of Blu-ray because it was only February when the high-definition format beat out Toshiba Corp.-backed HD DVD. Last week, the consortium kicked off a $25 million TV ad campaign to push Blu-ray, acknowledging in part that half the people it polled in a recent survey didn't know the format war was over.
Gains in Blu-ray revenues, including rentals and sales, are expected to counter some of the expected 6 percent decline in regular DVD revenue in the U.S. in calendar 2008.
Through the first three-quarters of the year, video rental revenue in the U.S. was down 1.2 percent at $5.6 billion and sales were down 3.5 percent at $8.6 billion, according to the industry tracker, Video Business.
Economic headwinds remain a concern.
In a survey the consortium conducted in late August and early September of 2,200 owners of high-definition TV sets in the U.S., U.K. and Japan, just 12 percent said they were likely to buy Blu-ray players in the next six months.
Another 30 percent were open to purchasing them, it said. How potential Blu-ray consumers will respond to lower prices isn't clear.
"This was done before prices started to come down and before the economy started to hit," Chris Lang, senior vice president of research firm SmithGeiger LLC, told the panel.
Those who don't yet have high-definition sets are not expected to be large contributors this season, said Bob Chapek, president of Walt Disney Studios Home Entertainment Worldwide. Purchasing a $1,000 high-definition TV and even a moderately priced Blu-ray player may not appeal to some buyers in the slowing economy, he said.
"It's only logical to expect there'd be some economic impact," he said. But he added, "We've been pleasantly surprised so far."
The consortium said a growing proportion - now about 10 percent - of home video sales comes from Blu-ray. In October, as the U.S. financial crisis came into focus, sales of Blu-ray discs more than quadrupled to 2.2 million units, it said.
A number of upcoming titles are riding on the format, including Warner Bros.' "The Dark Knight" due out in December.
Previous top-selling titles, such as "Iron Man," "The Incredible Hulk" and "Hellboy II: The Golden Army" have had a strong appeal among PS3 owners, and that raises hopes for a December turnaround.
"Every week as the next title comes out, we're all holding our breath," Kornblau said.
