Until they do day 1 exclusives, they will never truly “respond”.
They won't do day 1 exclusives for the foreseeable future, but I think they might implent a policy of adding all Sony published titles temporarily/permanently to PS Now within a set timespan from release. Like for example, that all must appear temporarily within 18months and be added permanently within 36months after release. The lower budget/less popular ones could appear much earlier on the service, while the AAA stuff ofcourse would take longer/max time.
Obviously that won't be 'good enough' for many people, including yourself, but I think this is a realistic way for Sony to handle this and a nice reassurence to the users of PS Now.
