IBTimes tells more:
Sales of both long-awaited systems are not expected to meet demand until next year. The Wii launched Nov. 19; the PS3 made its U.S. debut Nov. 17.
Sony Corp. has said it will have about 1 million PS3 systems for North American stores by the end of the year. Nintendo said it will have shipped 4 million units.
"We've shipped retailers several times the amount of hardware the other company was able to deliver for its launch around the same time - and we still sold out," Nintendo of America President Reggie Fils-Aime said in a statement.
Well, Nintendo Wii is 50% cheaper than that of PS3. That explains it.
