Ive actually considered posting about this before, there’s been several leaks leading up to this suggesting that two new controllers were in development. Basically there are some people who closely monitor files uploaded to steam, and sometimes assets and files are visible publicly for a short time. The guy who’s a source on this has accurately leaked stuff before, and it’s my belief we can trust him on this.
I wish Sony would just back off. It’s clear that they’re willing to drag their studios through mud to push PSN and other stupid requirements, and I hope any new studios they try to acquire will be paying attention to that.
