At a briefing ostensibly about Microsoft’s new dashboard and community gaming initiatives, the company’s director of Xbox 360 product management boasted that fewer and fewer former PlayStation exclusives are remaining PlayStation exclusives.

“We have a white board that lists all of the games people said we’d never get,” he told a roomful of reporters. “That list is getting smaller.”

His pride was well-placed, given that Square-Enix announced today that “Final Fantasy XIII” will be coming to the Xbox 360 when the game launches… whenever it’s coming out.

So I asked Greenberg when Microsoft would be announcing that “Metal Gear Solid 4” would be coming to the Xbox 360. It is the only major PS3 third-party game still exclusive to Sony’s system.

Greenberg laughed and said: “That’s a question for Konami.”
