Some of Microsoft's claims to developers may not pan out, though. Officials at game companies debunked Microsoft's assertion that Xbox is easier and costs less for developers compared with PlayStation 2.
"I wouldn't say there are any great differences in developing games for any of these platforms," said Bobby Kotick, chief executive at Activision Inc.
Microsoft has to overcome Sony's head start in selling consoles, which gives game publishers a bigger customer base. Sony could sell as many as 30 million PlayStation 2s by March 31, compared with 7.5 million to 6 million for GameCube and 6 million to 5 million for Xbox, said Larry Probst, chief executive of Electronic Arts Inc.
Widely anticipated PlayStation 2 titles expected to go on sale later this year such as "Metal Gear Solid 2" will compete with the first Xbox games, which aren't likely to demonstrate the system's capabilities, he said.
As Microsoft assumes the unfamiliar role of upstart, history could be on its side. Console makers such as Nintendo, Atari and Sega Corp have failed to retain their advantage when introducing more advanced systems.
"No one's been able to hold the lead successfully," Griffiths said. "That should make Microsoft feel good about their chances."
