Xbox Holiday Sales StrongLAS VEGAS (Reuters) - Microsoft Corp.s video game chief on Wednesday called the holiday season "very good" for the Xbox game player, but shied away from setting a launch date for the widely anticipated game, "Halo 2." In an interview with Reuters, Chief Xbox Officer Robbie Bach also said Microsoft was unconcerned about rapidly increasing hardware sales for its closest video game competitor, Nintendo Co. Ltd. "Christmas was good, we feel like we had a very good holiday," Bach said. "I think it was one of those holidays you would describe as solid." Bach claimed Microsofts Xbox outsold Nintendos GameCube in the last two weeks of December, despite GameCubes lower price, $99 versus Xboxs $179. Nintendos move to a $99 price spurred a boom in GameCube sales that brought it closer to second-place Xbox in terms of U.S. installed base of users. Bach, in Las Vegas for the annual Consumer Electronics Show, declined to commit to a launch for highly touted "Halo 2." The original "Halo" is the Xboxs top seller, and most expectations have been for the new game to come out in early April or thereabouts. "Were going to ship it when its ready," Bach said. "That might be the first half of 2004, it might not. You have to be careful with franchises like this." He also downplayed speculation that the Xbox -- with new software to play back music and pictures from a PC, and other expected enhancements -- was morphing from a video game console into a home entertainment device. "Its not Xboxs role to be the center of what we do in the living room at home," he said. FEW DETAILS ON XBOX 2 The industry is eagerly awaiting any word on when the next generation of console video game players will arrive. Most expect market leader Sony Corp., as well as Microsoft and Nintendo, to bring out new consoles in 2005 or 2006. Sonys PlayStation 2 had a one-year head start on the Xbox and GameCube, an advantage that has proved insurmountable, in terms of installed base and market share. Microsoft has of late been actively hiring engineers for its development efforts. "Really, the imperative is to not give anyone a head start," Bach said. He declined to offer further details on Microsofts announced partnership with International Business Machines Corp. (IBM.N: Quote, Profile, Research) or to discuss issues like whether or not the next Xbox would contain a hard drive, as the current unit does. Many analysts have cited the hard drive as a key cost of the money-losing console. He also said it was unlikely Microsoft would make any major hardware upgrades to the Xbox before the current business cycle ends, as Sony has done with PS2. "They do their tuning with hardware, we do our tuning with software," he said.
