That said, I don't know if this is necessarily a good thing either. Strictly as a video game publisher, Microsoft has been doing pretty well for themselves over the last five years. They've definitely stood out as one of the more consumer-friendly publishers, but the market is full of notoriously bad publishers (Bethesda included) so being one of the better ones isn't very praiseworthy.
Microsoft also has their own jaded publishing history which includes some pretty bad moves at the end of the 360 generation and beginning of the Xbox One generation. The Kinect was a very high-profile failure. The original Xbox One was met with a strong backlash for lacking support for physical media. They played a significant role in the integration of "microtransactions" into full priced video games. Although they have done many great things over the last few years, I'm still weary of them as a publisher.
I think the jury is still out on whether this is a net positive for the video game market, but it will definitely make the upcoming console generation very interesting.
