Bach Calls Sony Out!"Whenever Sony launches, Im ready" - Bach Xbox boss lays down the challenge to Sony at X05 Microsofts chief Xbox officer Robbie Bach has thrown down the gauntlet to rival platform holder Sony, telling GamesIndustry.biz that the firm is ready for Sony to say "which market, what date" for the launch of PlayStation 3. Speaking at the X05 event in Amsterdam this week, Bach said that Sonys vagueness about its plans for PlayStation 3 meant that Microsoft couldnt say for sure what size of lead it wanted to have in the market by the time the rival system arrives. "Instead, really what I say is, whenever they launch, Im ready," the bullish Microsoft executive commented. "They should just tell me which market, what date, and Im happy to be there - and well already be in that market, it turns out." Bach also reiterated Microsofts claim that Xbox 360 is just as powerful as the PlayStation 3, which will launch at least six months after the arrival of the Microsoft next-generation system. "I think the reality will be that a game on Xbox 360 and a game on PS3, thats cross-platform, the power that theyre going to get from the PS3 and the power that theyre going to get from the Xbox 360 are going to be about the same," he said. "You know, weve done the math. We have silicon engineers too. Weve done the math on their specs and our specs and we think theyre about the same."
