Early PS4 success doesn't worry Microsoft

The early success of the PlayStation 4 doesn't worry Microsoft, according to the company's corporate vice president of Europe Phil Harrison.

He insists that there is a plan in place to keep the Xbox One performing well throughout its lifecycle.

"We're 120 days into our platform lifecycle," he told GamesBeat. "You know better than anyone that this is a marathon, not a sprint.

"We're happy with our plan. We're happy with the performance of our key franchises and key partnerships, most notably Titanfall in the last couple of weeks."

Harrison claimed that the next few months will also see a bunch of new game announcements for the platform.

"We have some big announcements that we're going to unveil to the world in the next few months at E3 and Gamescom. It's show season again."
