In case you haven’t noticed, Microsoft’s Xbox One policies on connectivity and used games have caused a little bit of controversy among gamers. And now Piper Jaffray analyst Michael Olson has told The Wall Street Journal that Microsoft’s decisions may have upset gamers enough for him to consider cutting his sales forecasts for the Xbox One and raising them for Sony’s rival PlayStation 4.

“Based on what we’ve seen now, the likelihood that Xbox One will be able to overachieve those estimates is low, and Sony’s ability to overachieve that is higher,” Olson told the Journal. “It’s a big enough deal that it could impact adoption and will impact adoption.”

The Journal also talked with IDC analyst Lewis Ward, who said that companies that have tried implementing such restrictive policies in the past haven’t “stopped piracy” and have instead “alienated gamers.”
