There are about 100 Million households in the United States ... What we know is that there are about 7 Million PS3s purchased in the United States which were primarily purchased to play videogames, while at the same point for DVD there was 4.5 Million DVD players that were only purchased to watch movies ... an amazing victory for Blu-Ray indeed!
Blu-Ray is going to become the dominant format in a similar way to how HDTV will become the standard ... HDTVs entered the market and stayed a niche product for a very long time while LCD TVs (which were not HD at the time) saw massive sales because they were larger TVs that were thin and light. Soon enough almost all LCD and Plasma TVs were HDTVs and HDTV sales skyrocketed to a level roughly equal to LCDTV sales + HDTV sales. Soon manufacturing prices on LCD and Plasma TVs were comming down at a rate where it was cheaper to produce a HD-LCD TV than a similar sized SD-CRT so manufacturers stopped producing SD-CRT or SD-LCD TVs and you can only buy HDTVs ... Eventually, Blu-Ray will become the dominant format because people will go shopping for a DVD player and find out that a $20 Blu-Ray player plays DVDs and no one sells DVD players anymore.
