Quite a bit of interesting information from this article. It looks like Sony is once again leading the way for new IP's. It confirms that HFW is still slated for the second half of the year and will be utilizing haptic feedback, it reveals that Ember Labs is already working on their next project, highlights that PS5 game sales are 11% higher than PS4 sales in a comparable time period, and much more! Here's the quote about the SIE pipeline:
"According to Hermen Hulst, a Guerrilla cofounder whom Jim Ryan tapped to lead PlayStation Studios in 2019, the group has more than 25 titles in development for the PS5—nearly half of which are entirely new IP. “There’s an incredible amount of variety originating from different regions,” Hulst says. “Big, small, different genres.”
What's interesting about this number is the article clarifies Housemarque as a third party studio, rather than grouping them as a first party studio, which Sony tends to do with games they're publishing.
"Housemarque isn’t even a first-party developer; what’s coming from the collection of companies under the PlayStation Studios umbrella bears out the breadth and depth of the pipeline."
Even if you consider that a few SIE studios have multiple teams, 25 internal projects seems like a lot, and if they aren't including partnerships, it does seem like Sony is keeping a few acquisition(s) under wraps.
